Yes, that is tricky, but assuming we do, I have some questions.

These are Mailman generated Message-IDs indicating the message is some
kind of Mailman generated notice and not a list post. Are they all like
that or are some of them list posts?

I could recognize this in simplematch

with a start regexp of

^.*This is the bounce program. I'm afraid I've been instructed

and an address regexp of

^Delivered-To:\s*(?P[^\s@]+@[^\s@]+)\s*$')

Here is a sample of one semi-regular bounce I get from a list I manage
(I haved X'ed out the personal information included in the bounce). I
suspect that one issue is that this is a bounce message, not a server
refusing (thus they are probably back-scattering), and the bounce
doesn't give the address that the message was sent to (though it is in
the Delivered-To: header of the message that bounced that I trimmed).

Also, being a 'I think your a spammer' as opposed to 'That address isn't
valid' message says I am not sure one really wants to count it as a bounce.

Most likely (you can tell by looking at them) they are spam sent to the
listname-bounces address. They might also be out of office type
responses sent by non compliant (RFC 5230) vacation programs or replies
to list mail erroneously sent to the envelope sender.

What causes them is any message sent to a listname-bounces address that
is not recognized as a delivery status notification by Mailman's bounce
processing. At this point actual unrecognized DSNs are very rare, but if
the message looks like a DSN and is unrecognized, you can post it here,
and we will try to update the recognizers to recognize it.

You can set a list's Bounce processing ->
bounce_unrecognized_goes_to_list_owner to No to eliminate the notices
from that list, but then you will miss any real bounces which are
unrecognized if there are any.

The only harm is the extra mail to deal with.

The increase is probably due to an increase in spam possibly due to
various listname-bounces addresses getting on more spammers lists.

[Mailman-Users] Questions About Uncaught Bounce Notifications

[David Andrews]

I run an installation that has over 300 lists.  Normally, for years, 
I received around 300 uncaught bounce notifications a day.  In the 
past couple of months, it has dramatically increased to 3000 to 4000 
a day.  Some questions:  what causes them? Can they be reduced? Do 
they hurt anything? Toes the increase mean a problem somewhere else?


Thanks!

Dave

First of all, the primary support resource for this package should be
RedHat. See .

That said, see 

What you want in mm_cfg.py is

DEFAULT_EMAIL_HOST = 'fdu.edu'
DEFAULT_URL_HOST = 'fdu.edu'
VIRTUAL_HOSTS.clear()
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

The second line above, DEFAULT_URL_HOST should be set to whatever host
name you want for accessing the web UI.

Then, if you have existing lists, you need to run Mailman's

bin/withlist -a -r fix_url

to update those.

Re: [Mailman-Users] Include part of message when rejecting due to excessive size?

No. The message that is sent is built from the 'refuse.txt' template. It
includes the provided reason, but the only thing from the message is the
Subject:.

You could copy/paste parts of the message header and/or body into your
reject reason. Anything else would require code modification.

[Mailman-Users] Include part of message when rejecting due to excessive size?

[David Gibbs via Mailman-Users]

My memory is failing me... I thought that, when rejecting a message from
the admin queue, part of the original message was included in the reject
message.

Is this true?

When I reject messages, just the reject message is sent.

If so, is there a setting that I need to adjust?

If not, is there any way to do that?

Thanks.

[Mailman-Users] Need assistance configuring Mailman version 2.1.15 on RHEL7

[Mr. Vishal Gandhi]

We installed Mailman version 2.1.15 on RHEL7 using yum. We don't want mailing 
lists' email addresses with the same domain as the server has. For example: 
server is example1.fdu.edu . We would like to have email addresses of the 
mailing lists to end with @fdu.edu so that someone sends email to li...@fdu.edu 
and the subscribers of the the mailing list list1 will receive it. Can some one 
please provide us some guidance on how can we accomplish this?

We'll appreciate any help or guidance we may receive.

Thank you.
