[SM-USERS] "From" and "To" columns
Hi, is there any way to create folders where i can save sent and received mails and see them correct with "from" and "to" columns? The problem is that if i save sent messages with received ones in a folder i only see "from" and so i know i have sent them but i dont know whom i sent them. The best solution would be to have two columns in a folder one with "from" and one with "to". Is this possible? Has anybody experience with that??

[SM-USERS] Undefined offset: %d in filters/filters.php line %d
Hello! I'm deploying SquirrelMail at work and at my private server for my users to read their mail in. And recently I heard that some of my users are experiencing 'problems' with their mailfilters (from the filters/filters.php plugin). I'm not sure if this is the correct place to query about this, but since the plugin came with the distribution of SquirrelMail both on Debian and on FreeBSD, I gather it's ok :) Okay, so, on random moments my users report seeing the message: PHP Notice: Undefined offset: 1 in [path]/plugins/filters/filters.php on line 280 This, ofcourse, only happens to users who use filters to move mail away. Google isn't really very helpful, and neither is marc.theaimsgroup.com. It looks like the data returned by the IMAP server fails some expected format, since it fails in a call to explode() on $read[], and $read holds the result of an imap connection... Has anyone ever experienced this problem, or does anyone have a solution? I tried fiddling with the configuration in filters/setup.php, but $UseSeparateImapConnection = true; didn't help much either. Even though PHP 'notifies' about this filter-thing, the messages do get moved, and there's no mail getting lost, its just a nasty error on some random occasions.. Unfortunately i've been unable to reproducte the problem. One thread I found was about the filters going mad when there are messages to 'filter' but none match the stored filters, I was unable to reproduce that too... Any clues?

[SM-USERS] SquirrelMail for 4K users
Hello Everyone, The idea of paying MS thousands of dollars in licensing fees to run Exchange using OWA is way over our budget. So, I am looking into possibly using SquirrelMail to provide web mail access for our website members it is currently running on a Dell 2400 Power Edge dual processor, scsi, 60 GIG HD, 1.5 Gig RAM using White Box Linux 3.0 ES for my OS. I have read the FAQ's for enhancing SQM performance which I intend to use. I will be using the latest Postfix with MYSQL for my MTA with spamassasin handling spam including clamav for virus filtering all in one box due to budget limitations. Do you currently use SquirrelMail to handle web mail for thousands of users? What issues have you run into and what have you done to resolve them. Any suggestions, ideas to meet this undertaking will be appreciated even being RTFM'ed : ) Apologize for the long e-mail. Thank you, for your time! Joe
[SM-USERS] Warning: ftp_put(): .procmailrc: Overwrite permission denied
Hi, i tried to plugin the procmailfilters in squirrel, but i get the following message when the file .procmailrc does exist in my homedir: Warning: ftp_put(): .procmailrc: Overwrite permission denied in /var/www/localhost/htdocs/squirrelmail/plugins/procfilter/procfilter_options.php on line 253 But ftp_put works, because if the file doesnt exist in my homedir then squirrel will create it correct. The file permissions are 777 so everybody could change it. I also changed the home directory to 777, and i always get this error. I would be pleased if somebody could help me.

I've found this is the biggest performance factor for a mail server, at least in terms of what the user experiences (i.e. they rarely notice if an email takes 5 minutes instead of 30 seconds to be delievered but they definitely notice if it takes 30 seconds to login and see their INBOX of 3000 messages). I'd stay away from UW-IMAP at all costs. Look into Courier or Cyrus for a reliable, fast IMAP Server. > > Do you currently use SquirrelMail to handle web mail for thousands of > users? ~1500 fac/staff and students for a small university. We're running Courier and Squirrelmail on a 1.5ghz P4, 768mb ram, 40gb IDE RAID1. Not the best specs for a server but it runs like a champ. > What > issues have you run into and what have you done to resolve them. Any > suggestions, > ideas to meet this undertaking will be appreciated even being RTFM'ed : ) Courier and Squirrelmail have proven to be quite stable. Not to many issues. Do some testing before opening it up to 4000 people (maybe a beta group?), Keep good backups, use the server regularly yourself to keep an eye out for performance issues or problems.

Some FTP servers allow you to disable explicit overwriting, and you have to delete the file before you can upload a file with the same name. For example ProFTPd has that option, and can be disabled using: AllowOverwriteon I suggest checking the documentation for the FTP server you're using, or alter the code for the procmailfilter, and above the line you get the error, put an ftp_delete. -- Jonathan Angliss ([EMAIL PROTECTED]) Posting Hints: http://www.squirrelmail.org/wiki/en_US/MailingListPostingGuidelines --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

Hi John, I now feel more confident deploying Squirrelmail after receiving positive feedbacks from fellow Squirrelmail users. Thanks a lot everyone for all your inputs!

In my opinion, given that you've only got PIII's in that box, you've got too much for it to handle. It can certainly handle the mail (provided that 60GB disk is actually some form of RAID), but I've found the squirrelmail/IMAP end to be more cpu-intensive than one might expect. (But note that you wouldn't be able to run Exchange on that config either.) In our configuration, we've got a Dual PIII 1000+2GB 2450 as the MTA/IMAP/POP3 box for ~4,000 users and 3xPE1550's with single PIII 1000's+1GB load balanced for SQM with about 1000 daily SQM users and each web server serving around 50k hits daily. We're not using any PHP optimizers yet. On the IMAP end, things can slow down to the point where the web application has a noticeable performance hit as well, but that's rare. We deliver around 50,000 emails/day to these 4,000 accounts. Some notes: - With 4,000 users depending on one application to access their email, you must have hardware redundancy. Load balance several lower-end web servers (with LVS or something) rather than having one beefy box. - With 4,000 users, depending on how much they use email (probably a lot!), make sure you've got a good I/O path to your storage. U160 SCSI at a minimum, some sort of striping/mirroring preferable. We've got a 14-disk JBOD hooked up to a PERC4/DC and it performs nicely, but on our former array, a 4-disk RAID-5 over U2W on a PERC2/DC, performance was unacceptable. Avoid RAID5 if possible. - Use a PHP optimizer on your frontend. - Keep the IMAP service and SQM on different hardware if at all possible: both can be cpu-intensive depending on the options you enable. - Note that our 3 node LVS cluster serves 1,000 users nicely and you're talking about 4,000 users. Sorry to be the bearer of bad news here -- I just don't think you have the hardware to do it. For such a number of users, the end-to-end design has to be scalable and resilient.

Re: [SM-USERS] SquirrelMail for 4K users
I tend to agree. I'm (trying) to run SM on a dual processor Sun with 4 GB, solely as a web client (IMAP and smtp are elsewhere) and 300 or so simultaneous users uses up all the processor. And that's with a PHP accellerator (Zend). I'm still poling around trying to find some way to make this work without investing in some powerhouse 8-cpu machine.

If your INBOX has 100K pieces or even 10K pieces of messages, it will be slow. SM 1.5.1 seems to fix this problem but it is not a stable release yet. If SM can work directly with DBmail, accessing DBMAIL directly instead of IMAP, it will be the fastest thing you will ever see. Robert --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

[SM-USERS] Re: Missing messages in message list
I agree, it's always with a message that I *just* read. Today, it was with a list digest message that has a dozen or more messages attached to it; I figured that maybe reading all the attachments triggered the bug, but couldn't reproduce it. I'm glad that it's not just me! /jason On Wed, 8 Sep 2004, Bob Cottingham wrote: > I've been seeing this regularly as well. I'm running 1.5.1-cvs from about > three weeks ago.

[SM-USERS] forwarding problem ?
Hi Some users said they have problems when forwarding emails with attachments. I am new to SM so is it a known bug or "users legend" ?

Re: [SM-USERS] forwarding problem ?
Some users said they have problems when forwarding emails with attachments. I am new to SM so is it a known bug or "users legend" ? I've heard such complaints before, so perhaps they are having legitimate problems. However, since you give not a spec of useful information, I have no way to help you whatsoever. Please read: Posting Guidelines: http://squirrelmail.org/wiki/wiki.php?MailingListPostingGuidelines Of note are the list archives; maybe your question already has an answer out there. --- This SF.Net email is sponsored by: YOU BE THE JUDGE.
