duplicate dkim headers w/ AWS SES
by sunil soprey June 3, 2020

June 3, 2020

Periodically, I've seen these errors from few senders, and wondering if community has a idea? Mailman - 3.3.1rc1 Tom Sawyer "554 Transaction failed: Duplicate header 'DKIM-Signature'" while sending AWS-SES as the MTA? Possible to strip from postfix? I've submitted a AWS ticket.

Emailing a list from the list server
by Mark Dadgar June 1, 2020

June 1, 2020

Ok, I admit I am baffled by this one. I cannot email a list from an account on the list server itself (for example, programmatically by script, but also manually) using mail / mailx / mutt / etc from the command line. The emails just disappear into the ether. I can email other arbitrary addresses just fine, including real users hosted on that server. Here’s the postfix main.cf section for mailman3: owner_request_special = no transport_maps = hash:/var/lib/mailman3/data/postfix_lmtp local_recipient_maps = proxy:unix:passwd.byname $alias_maps hash:/var/lib/mailman3/data/postfix_lmtp relay_domains = ${{$compatibility_level} < {2} ? {$mydestination} : {}} hash:/var/lib/mailman3/data/postfix_domains What obvious thing am I missing? - Mark ----- mark(a)pdc-racing.net | 408-348-2878

Header Filters
by Peter Adebahr June 1, 2020

June 1, 2020

Hi *, we are trying to dispose of automatic replies like "out of office" etc. For these ends, we have set Header to "subject" (w/o quotes) Pattern to ".*out.of.office.*" Action to "Hold for moderation" However, these mails are passed through to the list. How is this to be set to become effective? Thank you and have a good week Peter

I am curious (and perhaps this is in fact the issue) why when I run mailman conf I don't see the archiver.hyperkittty section even though its in the mailman.cfg file? While at the same time I do see archiver.{mail_archive,mhonarc}? I know it's reading my mailman.cfg based on other sections I've already setup/manipulated. Another data point: $ grep -i hyperkitty requirements.txt HyperKitty==1.3.2 mailman-hyperkitty==1.1.0 Any suggestions? ________________________ Bryan Loniewski Rutgers University OIT:EAS:Messaging and Collaboration Services System Administrator

automation of mailman3 core startup

Mailman rewrite the Cc header incorrectly
by Alan So May 27, 2020

May 27, 2020

I just notice that if I send an email to a list with a Cc header broken into multiple lines and the pair of double quotes are put in different lines, the email addresses afterwards will be wrongly rewritten. For example, CC: "ABC DEF (XYZ)" <name(a)example.com> It will become the following after going through the mailing list: CC: XYZ <"ABC DEF"@mail.server.name> It seems that Outlook often split the To/Cc header into multiple lines and they often add double quotes to the full name of the users. Is the rewriting of Cc header handled by Mailman's code or another Python class? Thanks. Regards, Alan So

Is there an Emergency Moderation function (similar to the one that Mailman 2 had) with Mailman 3 core/Postorius? Thanks, Brian

Migrating Mailman 3 lists
by Brian Carpenter May 26, 2020

May 26, 2020

Hello Mailman users, I know how to migrate mailman 2 lists to a new mailman 3 server. However I do not know how to migrate a mailman 3 list from one mailman 3 server to another one. Are there any instructions or protocol on how to accomplish this? The Mailman 3 server I want to migrate *from* was setup using Docker. The Mailman 3 server I want to migrate these lists *to* was setup using a python virtual environment via pip. -- Please let me know if you need further assistance. Thank you for your business. We appreciate our clients. Brian Carpenter EMWD.com -- EMWD's Knowledgebase: https://clientarea.emwd.com/index.php/knowledgebase EMWD's Community Forums http://discourse.emwd.com/

performance report - mailman 3.3.1rc1 / postorius 1.3.1
by sunil soprey May 26, 2020

May 26, 2020

Hi all - I just wanted to share my perf-load results of Mailman3. Hopefully community finds helpful. I realized mailman3 cannot run on AWS t3a* ( 2cpu or 4cpu @ 8 gigs ) Specs: AWS EC2 - m5a.xl and c5.xl Version: mailman 3.3.1rc1 What: Duration load test of 30k emails across 200 lists. Some lists have a depth of 9k users, other lists have 100 emails address. * create 200 lists of random names Results * Postorius kept hanging on vanilla AWS LTS and LTS2 image. I had to tune the kernel settings ( somax, syslimits, tcp wmem) * gunicorn.cfg must be created and workers/threads property must be added. I noticed hanging python and tcp/socket errors * Total run time = 50mins for fresh-load
