I've had quite a lot of bounces recently. This seems largely to have been
because my hosting company was having difficulty sending to Outlook (and
therefore maybe Microsoft servers generally). But I've been taking more
interest in the bounce messages as well.
These have included "Rejected by header based Anti-Spoofing policy" (an
organisation using Mimecast recognising its own email address in the From:
header), "DMARC Verification Failed" for a domain with p=reject (despite
dmarc_moderation_action being Munge From), "This email has been delivered to
the intended recipient, but our email system has identified that DKIM
Signing is missing or has been misconfigured. Please ask your IT department
to configure DKIM Signing to allow us to confirm the authenticity of your
emails." (despite the hosting company having the right DKIM record) and
I have added REMOVE_DKIM_HEADERS = Yes to mm_cfg.py and restarted Mailman,
and changed from_is_list from No to Munge From.
Nobody seems to mind that all emails are now from the list address -
reply_goes_to_list was already set to This list, and now the sender's own
email address now appears in the Cc: header.
Is there anything I could do as well as or instead of that?
I've been sort of casually looking for alternatives to Google Groups.
I subscribe to and/or help administer a number of groups there. There
are a large fraction of us who only ever use the email interface.
There are others who would leave (or get out their pitchforks) if the
web interface wasn't available. A couple of the groups are fairly
large, 3000-4000 subscribers, with archives dating back ten to twenty
years. Functionally, Google Groups is fine, but well, it's Google,
with all that implies. Most of the time everything is okay, then they
make a change to the web interface and all hell breaks loose for a
couple weeks or months until Google gets around to fixing the
I've been keeping an eye on Groups.io (subscribed to its group
managers list). It's not free, and would cost at least $2000/year for
the bigger lists. They have a donation interface to make it easier for
list admins to solicit donations to defray costs, but it's not clear
that always works as desired. The messages to the group managers list
seem to imply GIO has various other warts as well. (It does have a
clever #hashtag-in-subject feature for tagging related messages.)
So, I got to thinking... Are there any free web user (not admin)
interfaces which integrate with MM3? Something which when combined
with MM3 could conceivably be an alternative to Google Groups, (the
now defunct) Yahoo! Groups, or Groups.io? I poked around the archives
a bit and browsed list.org for a few minutes, but turned up nothing.
Or rather, all I found related to web interfaces was the admin
I'm seeking to replace an out-of-domain .forward file, which is
an outdated solution, with a secret mailing list with myself as
the only subscriber. So I have created the mailing list
thomas@domain, and I want the list address to let everything from
any genuine mail address through to me. Spam filtering happens
So I'm looking at:
List of non-member addresses whose postings should be
If I put this regex there: ^\S+@\S+$ would that accomplish what I
want -- letting everything through, only checking that the sender
address exists? (Even that check could be done elsewhere though.)
I'm configuring mailman3 with exim4 on a debian 11.
I followed the official documentation on mailman for exim. It seems to
be all rights, but I have a problem:
when I send a message to a new lists in exim logs I see that exim uses
correctly mailman router and transport.
Unfortunately in smtp.log in mailman3 log folder I have the following error:
May 04 16:51:01 2021 (2337) ('127.0.0.1', 34746) sender:

This causes that messages are not sent from mailman to users. Have you
an idea of the problem?
Can it be a memory problem that causes that mailman responses are too
slow and exim closes the comunication before the end?

When adding a mass subscription list is there a way to set a universal default for subscription options for all users/members being added? Any help you could provide would be greatly appreciated. Thank you!
