What we see with U Wash imap is the first connection getting killed by the second, because the mbox is read over NFS. Outlook Express does this two-connection dance every time it checks for mail, so if the user has it set to check automatically every 1 minute, you've got 120 user authentications a minute going on, in addition to the connections opened each time a message is read and needs to be marked seen. Compare to Mulberry or Netscape Communicator or Pine, and you will see they open one connection to select inbox and hold it open, using it to check for new mail, flag messages deleted and seen, and so on. Is this just a case of alternative designs? Does it make any sense at all to open a connection to change state and a connection to check state simultaneously-- does that sound like recommended programming practice for imap or anything else?

This is a necessity for us too, if we are to integrate the Exchange and Cyrus systems. One of the interesting things about Open-Xchange is support for push via SyncML. There is a list of PDAs that it works with. The devices we support now need the intermediaries of either GoodLink or BES attached to Exchange, and if I understand it right (I might not), they use a MAPI connection to find out when there is new mail. If so it appears they would work also with systems like Open-Xchange that offer MAPI connections.

As stated, normally done at the MTA level. But note also, normally done by total message size, not attachment size. If you have to analyze mime parts and measure the size of each one, half the battle is lost already, that is the sender already transmitted the large message and you had to store it in a spool file and parse it. At MTA level, if you and the sender both use ESMTP, your MTA can state its maximum message size in the ehlo response, and the sender's MTA can see that and not even send the message. That is the best outcome. If the sender does not use ESMTP, it wastes time sending the entire message, but you can still reject quickly. The sender's MTA will create the bounce notice, or do whatever else it does when mail can't be delivered. The Cyrus system should not send a bounce. It should only accept or reject, and the sending MTA should handle notifying the sender.

Hm. What if duplicate suppression is turned off? Infinite loop? Hop count is the classic MTA method of detection, but here the very first time around the loop will hit dup suppression. This calls for something else that lets the system know the message already passed through a local sieve script.

In case [1], user X forwards to an external address which forwards back to user X. This could be solved by not suppressing duplicates when forwarding to external addresses. Instead the loop would be stopped by exceeding the hop count in the MTA, and the MTA would bounce. This emulates what happens with .forward or .procmailrc loops. In case [2], user X forwards to user X. If lmtpd hands this to the MTA, it's like case [1]. Or does lmtpd handle this by itself? In that case the loop should be detectable, I imagine. I'm probably missing something. We might be smarter with case [1] if lmtpd inserted a "X-Been-Here" type header as it hands off to the MTA, so that it could detect a loop the first time the message comes back.

Matt Garretson <[EMAIL PROTECTED]> wrote: > Along similar lines, any well-written Procmail recipe which redirects > mail typically checks for, or adds, an "X-Loop" header before > forwarding anything. Yes, it's an old solution. The crucial difference is that if one writes a bad procmail recipe, the message loops round and round until one of the MTAs considers the hop count exceeded and bounces it to sender, but if one writes a bad sieve rule, the message _is silently lost_. That's a much harsher penalty. And we stand a chance of here of doing _better_ than procmail. If we insert a header roughly like 'X-Sieve-Seen: user hostname' when we forward, we can look for it in incoming messages and say we won't forward again. So the penalty for writing a bad sieve forward rule would be that it doesn't forward. That's better than bounce to sender, and way better than losing the message. > If the "editheader" Sieve extension gets implemented, then a well- > written sieve script should be able to do the same type of thing. > To me this seems a bit more sane than expecting lmtp or sieve to > accomplish it automatically.

Depending on how your system is set up, cyrus may have no way to verify who is sending mail, and would need to see that "anyone" has the "p" permission. This is no different than for any mailbox. All inboxes have an implicit "anyone p". > 2)How do you delete an entry from the bulletin board folder? > Since I had all rights I deleted a test mail I got into the folder by > dragging and dropping it in evolution.

Someone with the "d" permission can mark it deleted, and then expunge. I cannot think of any way to duplicate what you describe. It sounds like evolution is showing you something different from what is on the server, which would be pretty bad.

Since the copy failed, Squirrelmail did not send the delete command, and you don't know whether it would have worked. It would be simpler to debug if you configure Squirrelmail to just mark deleted when you tell it to delete-- no Trash. Second, stop doing ls on the filesystem. What you need to know about is Cyrus mailboxes and permissions-- not what's on the unix filesystem. Use cyradm to find out whether there is a mailbox called user.satimiscyrus.Trash, and if not, find out whether the ACL on user.satimiscyrus allows the user to create subfolders (the "c" permission). It would be weird for a user not to have permission to create subfolders of his own folders. That's probably not it. But you've been mucking around, so check. More likely COPY failed because Trash does not exist. Have the user create Trash with imap and see if that fixes it. Or use cyradm to create user.satimiscyrus.Trash. I assume that when Squirrelmail refers to INBOX.Trash it actually means a mailbox called Trash under user.satimiscyrus. If Squirrelmail wants to use Trash and it is not there, I don't know why it does not just create it instead of reporting an error, but I have seen other clients that dumb.

This reminds me of a concern that was raised about U Wash IMAP and storage of mail in unix home directories. In that setup IMAP access is based on unix file system permissions, and IMAP will open files that are not mail files if the user has unix file permissions to open them-- including various system files. This always struck me as a bogus concern since the user could also telnet in and see the same files! The protocol itself is no less secure than POP. I don't understand why POP is still around.

Re: limit tcp sessions opened by an IMAP client
Strange to see so many logins spread over a short time. They seem to be in pairs, which is the way some clients start up. I wonder if the client thinks the connection has dropped, and so it starts new sessions. I realize the server's netstat shows them as still connected. It might be interesting to log sessions and see what's going on. Or to strace live processes. And of course ask the user what it looks like from his/her end.

It marks the messages deleted. You can still undelete them, in case of error. Then the command "expunge" removes all messages marked deleted.

"Expunge" comes from the MM client developed in the 1970s. One of the developers, Mark Crispin, designed the IMAP protocol in 1986, and he carried over the term Expunge as the command to remove messages marked deleted. <http://www.columbia.edu/acis/email/mm.home/mmmanual/8.about.mm.html> I can't think of a good reason not to use the term that the protocol uses, since it is a word people know and using it would make it simpler to discuss commands applicable to any IMAP client. I first saw "purge" used in the mid 1990s. I don't know whether it first appeared in the Exchange Client (the interoffice memo and scheduling client that became Outlook) or Netscape Navigator (one the first GUI IMAP clients). It was an unfamiliar term and I did not understand why it was being used. None of the old email clients used it, nor did the POP or IMAP protocols.

Check this by looking at your syslog or maillog, for an outgoing message from <> to the hotmail address. It will be within seconds of the incoming message from the hotmail address. Actual delivery to the hotmail inbox is not your concern, and from stories I've heard, don't count on it to work. The hotmail user may have a user-level configuration that throws the mail away, without realizing it. If there are any other rules in the sieve filter before the vacation rule, check whether they say to stop. For example, if I say put mail from f...@example.com in inbox and stop, and then have the vacation rule after that, f...@example.com won't get the vacation message.

Holy expletive. By the time cyrus gets the message, you have lost the envelope sender and envelope recipients. So you can't send any type of delivery status notice correctly, whether vacation replies, bounces, or receipts.

Re: How to activate sieve script for users?
you dont need to known user passwords to set sieve scripts. The more interesting problem is how you will then maintain the scripts. Most users do not have the technical background to hand-edit sieve scripts. Instead they use a GUI to do this. But I'll grant that someone who could write .procmailrc recipes should be able to handle sieve. The GUI clients are write-only. That is, they can translate their own ruleset into sieve script, but they cannot translate back from sieve script. So you use the GUI, it stores its ruleset, and puts a sieve version to the server. When you want to update, the GUI reads its ruleset to show you what you have, and if you change something, it again puts a sieve version to the server. What we're doing here is implementing the web-based Ingo interface, and disallowing any other. This gets us at least the portability that the Ingo page can be accessed from anywhere, so that a user can update sieve rules from anywhere. (Actually the user is updating Ingo rulesets that are put to the server as sieve rules.) The down side is that some things you can really do with sieve itself are not available.

By the way, you need to define the functionality a little better. Do you mean drop all text/html parts and deliver the rest? That will result sometimes in empty messages. Or rewrite text/html parts into plain text? In most cases that will get you two text/plain parts. More likely you want to proceed conditionally on whether there is a text/plain alternative and whether that alternative has the same content (some do not). This might even be most appropriately done by the client.

Re: Problems with repeated download of messages from pop3
According to our field support here, this bug is fixed by downloading and applying all of the Service Pack updates. That is a really good idea anyway so harm done. I would like to know whether Outlook continues to have trouble after that. If so please let us know what version has the trouble. Cyrus is not doing anything wrong. Not only does the protocol allow numbers to vary in length, but the example in the RFC shows numbers of different lengths!

The tdlp.org 'MS Outlook to Unix Mailbox Conversion' MINI-HOWTO suggests that no Linux IMAP server using the Mailbox format supports this feature. Does Cyrus IMAP use the Mailbox format and, if so, does it therefore NOT support folders containing both messages and subfolders? By 'Mailbox format' they seem to mean 'mbox' format. When that format is used, a 'mail folder' is either a directory containing other folders or a file containing messages. Cyrus does not use mbox format, and its 'mail folders' can contain both messages and other folders.

cyr_expire error
cyr_expire has started failing with this error:
cyr_expire[4729]: IOERROR: bboard zero index/expunge record 4/1591
This is 2.3. Here's the info from cyradm:
localhost.columbia.edu> info bboard
{bboard}:
expire: 180
lastpop:
lastupdate: 17-Dec-2006 20:42:17 -0500
partition: default

So this is a top-level shared folder, not under user/, and articles
should expire after 180 days.
The error is this in mailbox.c:
/* Copy over records for nondeleted messages */
for (msgno = 1; msgno <= exists; msgno++) {
/* Copy index record for this message */
memcpy(buf,
index_base + mailbox->start_offset +

syslog(LOG_ERR, "IOERROR: %s zero index/expunge record %u/%lu",
mailbox->name, msgno, exists);
return IMAP_IOERROR;
}
But bboard contains messages 309. to 704., not 4 to 1591. We are using
delayed expunge.
What should I look at?

No. For a few years we have been refusing or rewriting messages with nulls or bare returns, so only mail at least 4 years old was involved. Many of the messages involved were 10 years old or more. Amateurish Windows-based mail-sending software is still in use that sends junk like this. From the lack of trouble reports, I think it is text parts that are mainly affected.

Re: Moving mail into IMAP server and the Received date
--On Monday, February 19, 2007 16:32 +1000 RM <[EMAIL PROTECTED]> wrote: I've been experimenting with cyrus and some other imap servers which also exhibit this problematic behaviour: when I move the mail from a local folder to an imap folder under cyrus, my adjacent Windows/OutlookXp mail reader sorts the mail by "Received" date, and the date registered as "Received" is the time/date that the copy operation is carried out (ie: now) rather than the date that the mail was actually originally received. Outlook uses the internaldate attribute. RFC 3501 says: 2.3.3. Internal Date Message Attribute The internal date and time of the message on the server. This is not the date and time in the [RFC-2822] header, but rather a date and time which reflects when the message was received. In the case of messages delivered via [SMTP], this SHOULD be the date and time of final delivery of the message as defined by [SMTP]. In the case of messages delivered by the IMAP4rev1 COPY command, this SHOULD be the internal date and time of the source message. In the case of messages delivered by the IMAP4rev1 APPEND command, this SHOULD be the date and time as specified in the APPEND command description. All other cases are implementation defined. The relevant command is APPEND, and its description says: 6.3.11. APPEND Command Arguments: mailbox name OPTIONAL flag parenthesized list OPTIONAL date/time string message literal [ . . . ] If a date-time is specified, the internal date SHOULD be set in the resulting message; otherwise, the internal date of the resulting message is set to the current date and time by default. So when a client moves mail from local to server, it *could* send an internaldate. Cyrus honors this. When we moved from U Wash to Cyrus we were careful to get the internaldate from U Wash and send it in the append command to Cyrus. When the client does not send an internaldate, Cyrus follows the RFC and assigns the current date and time. There is no imap command to change internaldate once it has been assigned. Ideally you might be able to find a client that sends internaldate when it moves mail from local to server. The catch is that since so many clients, like Thunderbird, do not use internaldate to sort, they probably don't preserve it in local folders, and they probably don't try to reconstruct what it was from Received or Date headers when they append to a folder on server. It's not really a Cyrus or Outlook bug.

Exchange's handling of Sieve Reject
Users on two separate Exchange servers here have reported that they
don't see the reason part of messages rejected by sieve.
The Cyrus user has a reject rule. I can reproduce it simply as:
##INGO
# sieve filter generated by Ingo (March 14, 2007, 8:51 am)
require "reject";
# Sieve Reject Test
if header :comparator "i;ascii-casemap" :contains "Subject" "please reject
this message" {
reject "You want it rejected, you get it rejected.";
stop;
}
-
To see precisely what is returned, send mail to [EMAIL PROTECTED] with
the subject "please reject this message". The mime message looks
syntactically correct to me, as follows:
main message is multipart/report
part 1 is text/plain
part 2 is message/disposition-notification
part 3 is message/rfc822
The Exchange messages were viewed with Outlook. Outlook users did not
see any of the message sent by Sieve, but only a new text generated by
Exchange or Outlook that looks like this:
-
From: Mail Sieve Subsystem [mailto:[EMAIL PROTECTED]
Sent: Tuesday, March 13, 2007 5:20 PM

Notice the changes in the line spacing, the Sent: line, the "was" line,
and the inclusion here of the text from mime part 2. Evolution also
indicated the presence of a dat attachment after this, which the Outlook
users did not see.
We did not yet test what Outlook shows when it reads as an imap client
off the Cyrus server. All the above was read off an Exchange server.
Possible fixes would be to format the rejection like a reply or a

anyone else dealt with this at all? Any bright ideas?

Deleting mailboxes on master
We cut over from a primary to a replica, and then back again, all within one outage, because we got the primary going again pretty fast. Now we have an interesting situation. The replica told the master about some obsolete mailboxes that no longer exist on the primary. As a result the mupdate from the primary did not rewrite the location of these obsolete mailboxes. They really do exist only on the replica. The replica does not report to the master (if it did, it would fight with the primary about where mailboxes are). Therefore, the following do not change the master: running cyradm on the replica and doing deletemailbox; and deleting the mailbox with an imap client. I have a list of them from running ctl_mboxlist -d on the master. But I can't figure how to remove them from the master's mailbox list. Does anyone have an idea?

It's less painful if you can use Cyrus to do this stuff. I know :-) The main reason you might have to do this would be restoring entire mailboxes off backups. Given /var/mail/j/user/janedoe/folder1/folderA , Cyrus might have three mailboxes named user.janedoe, user.janedoe.folder, and user.janedoe.folder.folderA, but not necessarily. cyradm will show you what folders exist, in Cyrus's view, and it lets you create, delete, and rename mailboxes to make the Cyrus view be what you want it to be. Cyrus will move the files around in the filesystem accordingly. To do batch work a perl script can use Cyrus::IMAP::Admin to do what cyradm would do. When we migrated from mbox, we created Cyrus mailboxes for the directories too. For ~janedoe/mail/foo/bar (mbox file) we created both user.janedoe.foo and user.janedoe.foo.bar, even though the user had never stored mail in foo (since it was a directory). This seemed simpler than having to explain later that foo could be part of a mailbox name but not exist as a mailbox!

But analyzing the old file structure is not difficult to script. "find" gives a nice list. "if (-z $file || -d $file)", just create a Cyrus mailbox but skip the message moving tool. Detail will vary depending how the old mail was structured. We had to grab /var/spool/mail/user, ~user/mbox, and ~user/mail/* which might be common in U Wash for example. It might have been cool to test the first five characters in ~user/* for "From " to catch stray files not in the mail directory.

alt namespace
We are planning to move to Cyrus and running a test server.
Using altnamespace and unixhierarchysep, we see this as expected:
c namespace
* NAMESPACE (("" "/")) (("Other Users/" "/")) (("Shared Folders/" "/"))
c OK Completed
But this looks wrong:
c list "" "%"
* LIST (\Noinferiors) "/" "INBOX"
* LIST (\HasChildren) "/" "mailbox2"
* LIST (\Noselect \HasChildren) "/" "Other Users"
* LIST (\Noselect \HasChildren) "/" "Shared Folders"
c OK Completed (0.000 secs 10 calls)
Clients that use namespace will list the contents of Other Users
and Shared Folders twice if we use this configuration, once under
"" and once under their namespaces.
What's wrong here?

There answer may be "no" but unless you give an example of what you mean it's hard to know what you're really asking for. The default mailbox names created are Inbox, Deleted Messages, Drafts, and Sent Messages. I want to shorten the names to something like Inbox, Trash, Drafts and Out(box) respectively if I can. If Cyrus is creating them, change imapd.conf to change them. But those are usually created by clients.

Non-personal users
We are converting to Cyrus later this year. We're currently trying to figure out how to organize non-personal mailboxes. Many departments and divisions like to have incoming mailboxes for official mail to the unit, and we'd like to keep that separate from any one user's mailbox. They usually ask for a user account and want to share the password. But as a single user, they'd not be able to track what each person has seen, and any person could delete and expunge. This might possibly work for two or three people sharing a job duty, where essentially as long as one of them has seen and acted on a message, the others don't need to see it. But in many cases what they really want to do is direct mail for some project or function to its own mailbox, and then get everyone to be able to read all the messages. So sharing with acl's is more appropriate. It seems like we'd want to set up a base mailbox per department, and set acl's so that some few people per department can manage a tree starting there. These few would be able to move messages around, delete and expunge, create and destroy sub-mailboxes, etc. We'd like to make it easy for each unit to manipulate this and not have to submit a request to us. Is it better to do this in "user." space or public folder space? We can see pros and cons to each, but we have no experience to draw on. What is actually being done on Cyrus systems, and how well does it work?

Re: Message contains NUL characters ...
It's pretty easy to stop messages with null characters if you use Mimedefang, a milter. A built-in function called SuspiciousCharsInBody tags messages with either nulls or bare CR or LF. We've let this go but since we're testing a Cyrus server it looked like we should stop them coming in. We started rejecting them about 5 hours ago and it's a remarkably effective spam filter. It got about 9,000 so far. There might be a legit message in there but I can't see one, just eyeballing the subject lines. It gets a lot of Chinese porn spam, and also pirate software, Viagra ads, bank phishing, etc. I cannot tell how many had nulls and how many had bare CR and LF so this might be tangential to the null discussion. But certainly legit mail with nulls appears to be very rare.

Users just want spam to go away. They do not want to configure filters. They're not very good at it either: they usually just add the sender address to a blacklist, and that does almost nothing for them. It's not a security issue. It's annoyance reduction. If this list could possibly restrict posting to subscribers that would go a long way. That is pretty routine for lists.

Re: Retreiving folders size from clients
I wonder if there's a standard way for retreive folders size from the client side ? The protocol does not have a command for that, but the client could get the size of each message and add them. Many clients actually cache a local copy of the mailbox, and do their read and write from that, synching changes to the server. It's like they're always on offline mode to some extent. If a client does this, it can figure out mailbox size locally without asking the server. I believe Outlook is one of these.

CMU's graffiti
CMU has a tree called graffiti in which anyone can create new bboard mailboxes. How is this implemented?

Tiger Mail.app
People using Apple Mail.app that comes with Tiger are not able to see messages in shared folders. By shared I mean both other users' folders and bboard-type folders. Shared folders are listed, and they can seemingly be opened, but only message numbers are shown. The same people could see these folders previously with Mail under Panther, and they can still see them now by using other clients. Have others here seen this problem?

Re: Cyrus & Sendmail
Is there ANYONE on this list that has managed to get the latest sendmail and cyrus to work on either RHEL4 or CentOS4 or FC4? If so, would anyone be willing to share how they got it working ( specifically the sendmail relaying auth via saslauthd)? We've got sendmail with smtp auth working on Solaris and Cyrus working on RH. As an illustration of how separate the two things are, we don't even use the same servers. You probably should ask on a sendmail forum like comp.mail.sendmail.

Re: ACLs
Ken Murchison <[EMAIL PROTECTED]> wrote: I know I had to give "anyone" "p" on shared folders. I tried giving "p" to user "cyrus", but it somehow did not work, not sure why. Delivery is done from Sendmail via LMTP and I did setup auth-info, so Sendmail should have authenticated itself as user "cyrus". Is that the right way? The MTA needs to use the AUTH= keyword with the MAIL FROM command. It is this authid which is used when checking the ACL. Yes yes, but that is the trick! Suppose one's sendmail smtp server has authenticated a sender, and we find that the the message should relay to our Cyrus server, how do we tell Cyrus it was auth'd as that user? We'd welcome reference to any document on the subject.

Re: [POLL] pop3d/nntpd and IMAP flags
Ken Murchison <[EMAIL PROTECTED]> wrote: It would be fairly straightforward to have an option that updated \Seen state whenever a POP3 client issues a RETR command or an NNTP client issues a BODY or ARTICLE command. I'm on the fence whether this makes sense for POP. But we've used U Wash for a long time and marking them as seen has not raised any questions that I can recall, so that behavior must be what users expect or accept. My question is what do people think of the interaction between pop3d/nntpd and the \Deleted flag? Should these daemons ignore articles that have this flag set? Should a POP3 DELE command or a NNTP cancel message just set the \Deleted flag instead of expunging the message? The RFC for POP3 actually describes DELE to mean mark as deleted, and QUIT to mean expunge and quit. I have just learned after all these years that if QUIT is not sent, the server 'MUST' not expunge. But does any client make this optional? The braintwister is that POP mark deleted and IMAP mark deleted don't need to be the same thing, so maybe POP expunge and IMAP expunge don't need to be the same thing either. The practical problem is that POP-only users would have no way to really expunge if DELE and QUIT don't do it, so they'd accumulate mail until they run out of quota. And then what do they do? This touches on the infamous problem of users who blow away their inbox accidentally by using a POP3 client that defaults to DELE on server. It's tempting to mark deleted to solve that. But it seems to me only to trade one problem for another. What we need is user-controlled unexpunge, Ken!
