[Mailman-Users] Some mailing lists are stuck

[Dominik Hoffmann]

I have a couple of mailing lists on my mailman server that don’t forward 
messages to their members. There are no rules that would block them. It all 
looks like they are stuck in a queue, which would just have to be unstuck. Is 
there a command-line way of doing that?

Is it some lists or all lists?

See , particularly items 2.2, 6.2, 7,
8, 9 and 13.

[Mailman-Users] Nonsubscribers attacking one of my lists.

[Kenneth G. Gordon]

One of my forums has suddenly been inundated with posts to the list by 
non-subscribers, 
most of which seem to be coming from some homosexual list somewhere. 

These seem to be coming from every place in the world.

I receive notices from Mailman every time I check my e-mail listing of 4 to a 
dozen 
non-subscribers attempting post to the forum, and I have to go to my admin 
database and 
remove and block each one.

Is there some way to prevent these jerks from showing up in the database at all?

Set the action on Sender Filters for messages from non-members to discard, 
instead of hold. I had to do that a long time ago (Don’t reject or you will be 
generating back-scatter)

OK. I'll try that. 

I DO get messages from non-subscribers once in a while that I should pass on to 
the forum, 
but there are so few of those that at this point, I had better follow your 
advice.

Thanks,

[Mailman-Users] Digest mode.

[Kenneth G. Gordon]

One of my subscribers is complaining that he cannot activate the digest mode 
for his 
account. I can find nothing wrong in the admin database.

Where should I look for this problem?

[Mailman-Users] Bounce processing

[Kenneth G. Gordon]

Over the past several weeks, I have received many reports from Mailman 
concerning too 
many bounces from certain subscribers who are normally very active on one of my 
forums.

All of these "Bounce Action Notification"'s appear to be coming from only a 
very few ISPs, 
the big one being AOL, although also verizon.com is another one. In the past, 
gmail.com, 
and hotmail.com have been a culprits.

Is there any way to prevent these people from being essentially kicked off the 
forum until 
AOL, among others, gets its act together?

The best you can do is look at the bounces and see what the cause is. If
it is the message being detected as spam, you may be able to contact the
ISP and get them to adjust their filters and at least partially white
list you.

There might be some other issue happening that the notice might help you
with.

it depends on the reason that you're getting the bounces.  i get them all the
time.  sometimes they're just bogus anomalous nonsense {e, g a clearly
non-spam message rejected for "too much spam content}  i just ignore
those - those people must know about the idiosyncrasies of their ISP and
by staying with them accept their foibles. ... BUT.. if the bounce is because
your host has been blacklisted or is otherwise banned, you need to contact
your isp pronto and get them started on getting themselves re-approved.

It's basically a policy call. If it is a few known addresses, you can
add them to accept these non-members to white list. If you want to
accept some non-member but reject others, unless you can devise a filter
to distinguish, you need to review them all.

Check the message headers -- there might be common patterns.  Look for 
Received: headers with "unknown" -- this is a giveaway that the messages are 
using spoofed From: headers.  Also look at the From: address, sometimes these 
messages are coming from partitular domains.

There are spam filters and sender filters.  When the regexp matches, one 
option is to *silently* discard the message.

*If* you have access to the inbound MTA's configuration, there are things 
there that can drop or bounce the messages at that point.

Other replies have given good advice, but one thing not mentioned is
DMARC. If the bounces are of mail that doesn't pass DMARC. See
 if this is the issue.

You need to look at the bounce notices and determine the reason for the
bounces.

I believe AOL and Verizon are under Yahoo now. All of them have DMARC
records that will cause bounces if you don't have your DMARC settings set
correctly. What do you have the "Action to take when anyone posts to the
list from a domain with a DMARC Reject/Quarantine Policy." setting set to on
the Privacy options --> Sender filters page?

It is possible to "subscribe" to a list and set that address to "nomail". So, 
this participant can still send messages to the list but will not receive 
anything. Much better idea than manually going through all the messages held 
for moderation.
