Header settings and Gmail

Hi, We operate a mailing list on which many members use their Gmail address. In the default settings, this results in a warning and delayed delivery (and maybe marking as spam): status=deferred (host gmail-smtp-in.l.google.com[74.125.128.27] said: 421-4.7.28 Gmail has detected an unusual rate of unsolicited mail. To protect 421-4.7.28 our users from spam, mail has been temporarily rate limited. For 421-4.7.28 more information, go to 421-4.7.28 https://support.google.com/mail/?p=UnsolicitedRateLimitError to 421 4.7.28 review our Bulk Email Senders Guidelines. As a preventive measure, it helps to use DMARC mitigation action with “Replace From: with list address” and “ DMARC Mitigate unconditionally ”. But now some users are unhappy with the From header " Username via Test-liste <test(a)test-liste.org>". They would rather have their email address in it. Is there a solution with which Google delivers the mailing list messages without complaining, but the sender email address is also in the “From:”? Thanks Erik

Only Recent archive tab works after mailman upgrade

Hi, since I upgraded mailman to 3.3.9 (python 3.11.2) I have an odd issue on lists' archive page. Apparently only the Recent tab works. If I switch to Active or Popular I see the change in the url but page content does not refresh. I can not see any errors in browser console and in logs so I am quite clueless how to debug further :( Thanks for the ideas.

Where to put static files referred to from list Info page?
by Greg Newby 06 Aug '24

06 Aug '24

Hi friends. Some of my version 2.1 lists had some static files that were referenced from the list's HTML pages. I'd like to do the same for the lists now that they're ported to MM3. My question: Is there a place I can put these files within the Mailman directory hierarchy so they can be linked from the list Info page? I.e., under "Settings / List info / Long description" I'd like to include a <a href=...> to a file that's somewhere in a persistent location in the same directory tree as the Mailman web. I tried putting it under mm/var/lists/listname/ (where 'listname' exists, and is where templates go. This yielded a '404.' I confirmed I can add an href to the Long description, but don't know where in the Mailman3 directory hierarchy I can put the files. Thanks! Greg Newby

External MTA incoming mail: configuration
by Roland Giesler 06 Aug '24

06 Aug '24

I have mailman set up to send mail via an external MTA, which is supported by mailman and described in the documentation here: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h…. Specifically it says: |lmtp_host|and|lmtp_port|are parameters which are used by Mailman, but also will be passed to the MTA to identify the Mailman host. The “same host” case is special; some MTAs (including Postfix) do not recognize “localhost”, and need the numerical IP address. If they are on different hosts,|lmtp_host|should be set to the domain name or IP address of the Mailman host.|lmtp_port|is fairly arbitrary (there is no standard port for LMTP). Use any port convenient for your site. “8024” is as good as any, unless another service is using it. However, there is a practical problem with LMTP (to receive incoming email) which is as follows: The setup in mailman.cfg: lmtp_host: lists.fast.za.net lmtp_port: 8024 Now, lists.fast.za.net is the mailman server. The docs say that mailman passes these on to the MTA. However, the MTA (postfix) on box2.gtahardware.co.za has the following setting in it main.cf: virtual_transport=lmtp:[127.0.0.1]:10025 If I reply to a signup confirmation email for example, the mail is received and processed by box2.gtahardware.co.za, and it is not passed on to the mailman server. So what is meant by "but also will be passed to the MTA to identify the Mailman host" in the docs? If I change the config of the MTA (postfix) to be "virtual_transport=lmtp:[lists.fast.za.net]:8024", I assume the incoming mail will be forwarded, but how does postfix know that only the mailman emails should be forwarded and not all the other mail that the server at box2.gtahardware.co.za receives? This is quite fuzzt to me at this stage. Could someone help me with some clarity please?
