DMARC issue with Mailman List
by Terry Lund March 21, 2017

March 21, 2017

We are getting the following error for one of our users in one of our mailman lists. I've tried to figure out if one of the configuration options in Privacy Rules can be used to address this issue, but I am afraid I am not real clear on the implications of the relevent DMARC related parameters. Any insight or assistance would be much appreciated. Our configuration is that our web site integration with PayPal has PayPal sending confirmation emails to a mailman list called treasurer-alias, so that multiple people are aware of the PayPal transaction. ---------- Forwarded message ---------- From: MAILER-DAEMON(a)bounce.mail.unifiedlayer.com To: treasurer-alias-bounces(a)catoctinareaturners.org Cc: Bcc: Date: 16 Mar 2017 02:55:28 -0000 Subject: failure notice Hi.

Limit messages per user?
by Carl Zwanzig March 18, 2017

March 18, 2017

Hi, Just asking for completeness-- AFAIK there is no mechanism in either mailman 2 or 3 to limit the number of messages per day originating from a given member. True? A list I'm on (but don't manage), had something like 700(!) in 30 minutes from a buggy auto-responder. That was shut down, but the damage was done. Now people are screaming about how poorly the list is managed, etc, etc. Will even spam-assassin cover this? Thanks, z!

Email services in and out
by Andrew Hodgson March 17, 2017

March 17, 2017

Hi, I have a couple of issues with our Mailman setup not really with Mailman but the inbound and outbound mail delivery, and wondered if anyone could recommend a service which would help me. I am getting more and more spam through the system, a lot of it is rejected with SpamAssassin, but stuff sometimes gets through from a forged subscriber's email address. There is also backscatter from the various subscribe addresses etc. I would like to try and cut this down if possible, looking at inbound antispam services that work with Mailman domains. I could also do with getting an outbound email service which has good delivery rates to the big ISPs. This is working well for me right now, but there are occasional issues where one provider stops receiving the messages altogether, and it can take time to deal with this. In short, does anyone have recommendations for AV/AS email solutions that work inbound and outbound that play nice with Mailman? Thanks. Andrew.

Unsubscribe line missing
by Bill Healy March 17, 2017

March 17, 2017

Hi everyone, We are very new users of Mailman. Version 2.1.23 Our mailing list is made up of schools. Responsibilities within schools change frequently so list members need to unsubscribe when someone takes their job. Some members are reporting that the one click unsubscribe notice at the end of emails is not there and that they have to write individually to the list moderator to have their email removed. On the other hand, it is obvious that some members are successfully using the one click unsubscribe. Is there an explanation for this? Can anything be done about it? Thanks in advance for any advice.

%(confirmurl)s reference HTTPS?

March 12, 2017

I am using %(confirmurl)s in verify.txt and unsub.txt. In our current setup, these substitution symbols generate urls with that use http:// protocol. Is it possible for these variables to generate https:// protocol instead? Thanks, Greg

Archives are returning HTTP 403 (Forbidden)
by Dennis Carr March 11, 2017

March 11, 2017

Of late, I've just received word that my archives are returning HTTP 403 - forbidden. So nobody can see them. Checking the file system, it doesn't appear to be a Linux issue necessarily - permissions are set so anybody can read the directory. In general, /var is set 755, /var/lib/mailman and /var/lib/mailman/archives are set "sticky" for group and is root.list, and the archives themselves are set 664 (and associated dirs are set 775 sticky), all list.list. I'm a bit lost, and can use some direction here. Help me out? Thanks, -Dennis Carr

Server Migration Issue -- Only Some Members Receive Email?
by Greg Sims March 10, 2017

March 10, 2017

I recently migrated from RHEL 6 to CentOS 7. The migration seemed to be straight-forward by: - creating three mailman lists - for each of the list directories - copy files from the old to new server - list options and membership seems good I have an issue and have run out of ideas. [root@ray06 log]# cat /var/log/maillog.processed /var/log/maillog | grep 'Mar 9' | grep status=sent | wc 6176 109377 1554218 The above looks at our maillogs for email that was sent on Mar 9. The answer is 6,176 emails sent. We have over 20,000 subscribers total on our three mailman lists. It appears that only some of the subscribers are receiving email. I also looked at this from the perspective of one ISP -- gmail.com. [root@ray06 email]# cat /var/log/maillog.processed /var/log/maillog | grep 'Mar 9' | grep status=sent | grep gmail.com | wc 976 18544 254501 [root@ray06 email]# sudo /usr/lib/mailman/bin/list_members english-devotion | grep gmail.com | wc 4945 4945 110190 The maillogs show 976 gmail.com emails sent while one of our lists has 4,945 gmail.com members. Again it appears that only some members are receiving email. I looked at /var/log/mailman/* and things seem normal. I'm not sure how to proceed from here.

removing individual email headers from digest
by Jim Dory March 9, 2017

March 9, 2017

I got a request from a user that seemed to make sense: removing unnecessary email headers at the top of each message in a digest. So I googled it, but before implementing it wanted to make sure it was correct and wouldn't cause other issues by presenting it here for comment. The fields of each collected message that seem appropriate for removal would be the "To:" line, since that is in the digest header, the Message-ID: line since that means nothing to the end user, and the Content-Type as that probably means nothing to the end user. That would leave intact the Date, From, and Subject lines. So here's the solution I found by googling (would it work or is better way?), and commenting out lines to keep: main config is loaded is Defaults.py above it mm_cfg.py config loaded edit sudo nano /etc/mailman/mm_cfg.py with adding in the end: # removing frustrating headers, 2016 06 04 by OG2K # PLAIN_DIGEST_KEEP_HEADERS.remove('Message') PLAIN_DIGEST_KEEP_HEADERS.remove('Date') PLAIN_DIGEST_KEEP_HEADERS.remove('From') PLAIN_DIGEST_KEEP_HEADERS.remove('To') PLAIN_DIGEST_KEEP_HEADERS.remove('Cc') PLAIN_DIGEST_KEEP_HEADERS.remove('Subject') PLAIN_DIGEST_KEEP_HEADERS.remove('Message-ID') PLAIN_DIGEST_KEEP_HEADERS.remove('Keywords') PLAIN_DIGEST_KEEP_HEADERS.remove('Content-Type')
