autoresponse not sent
by shadiakiki1986＠gmail.com Oct. 22, 2018

Oct. 22, 2018

Hello. Newbie to mailman here. I tried out mailman3 today. My setup is - mailman3 suite using the docker-compose file from asynchronous.io - exim4 on the local machine and configuring it as smarthost using mailgun smtp server The emails to the mailing list are received by the subscribers, but the autoresponse is not being received by the sender (who is not from the subscribers list). I'm not sure if the problem is from mailman-core, settings from mailman-web, or from exim. The setting for autoresponse to posters is set to yes, with some text to be sent in the autoresponse message. The autoresponse grace period is set to "0d60.0s" (I was unable to set to "0" or "negative" due to error saying something like "could not update parameter") The "Acknowledge posts" in the "global mailman settings" is set to "yes". The "Acknowledge posts" in the list-based preferences is also "yes". Here are the exim logs after I send the email from the non-subscriber to the mailing list ``` 2018-10-19 15:13:32 1gDWSy-0004n7-VR DKIM: d=gmail.com s=20161025 c=relaxed/relaxed a=rsa-sha256 b=2048 [verification succeeded] 2018-10-19 15:13:32 1gDWSy-0004n7-VR <= shadiakiki1986(a)gmail.com H=mail-vk1-f171.google.com [209.85.221.171] P=esmtp K S=2416 id=CACk+RNtq_hu+M_ufoCJQFCtOWOD_DX0omdVJbKfva0w=n4Qhuw(a)mail.gmail.com 2018-10-19 15:13:33 1gDWSy-0004n7-VR => quotations(a)mailman3.akikieng.com R=mailman3_router T=mailman3_transport H=172.19.199.2 [172.19.199.2] C="250 Ok" 2018-10-19 15:13:33 1gDWSy-0004n7-VR Completed 2018-10-19 15:13:35 1gDWT1-0004nC-1I DKIM: d=gmail.com s=20161025 c=relaxed/relaxed a=rsa-sha256 b=2048 [verification failed - signature did not verify (headers probably modified in transit)] 2018-10-19 15:13:35 1gDWT1-0004nC-1I <= quotations-bounces(a)mailman3.akikieng.com H=ip-172-19-199-2.us-west-2.compute.internal [172.19.199.2] P=esmtp S=3847 id=CACk+RNtq_hu+M_ufoCJQFCtOWOD_DX0omdVJbKfva0w=n4Qhuw(a)mail.gmail.com 2018-10-19 15:13:35 1gDWT1-0004nC-1I => shadi(a)akikieng.com R=smarthost T=remote_smtp_smarthost H=smtp.mailgun.org [35.161.201.187] X=TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 CV=yes DN="C=US,ST=California,L=San Francisco,O=MAILGUN TECHNOLOGIES\, INC,OU=MAILGUN TECHNOLOGIES\, INC,CN=*.mailgun.org" A=plain C="250 Great success" 2018-10-19 15:13:35 1gDWT1-0004nC-1I Completed ``` 1. Is the signature verification failure due to mailman-core trying to send the autoresponse outgoing message? At first, I thought that the DKIM signature verification caused Exim to be dropping the autoresponse. So I set `DISABLE_DKIM_VERIFY=true` in exim, but still no autoresponse. Here are the exim logs after the sender sends the email ``` ^[[A2018-10-19 14:58:40 1gDWEa-0004Ww-QF <= shadiakiki1986(a)gmail.com H=mail-vs1-f53.google.com [209.85.217.53] P=esmtp K S=2410 id=CACk+RNvnfS+e+Uh-OSKjPB8oe+b1=efAJ6BSrc51jz_h9sVoFQ(a)mail.gmail.com 2018-10-19 14:58:40 1gDWEa-0004Ww-QF => quotations(a)mailman3.akikieng.com R=mailman3_router T=mailman3_transport H=172.19.199.2 [172.19.199.2] C="250 Ok" 2018-10-19 14:58:40 1gDWEa-0004Ww-QF Completed 2018-10-19 14:58:42 1gDWEc-0004Wz-R1 <= quotations-bounces(a)mailman3.akikieng.com H=ip-172-19-199-2.us-west-2.compute.internal [172.19.199.2] P=esmtp S=3841 id=CACk+RNvnfS+e+Uh-OSKjPB8oe+b1=efAJ6BSrc51jz_h9sVoFQ(a)mail.gmail.com 2018-10-19 14:58:42 1gDWEc-0004Wz-R1 => shadi(a)akikieng.com R=smarthost T=remote_smtp_smarthost H=smtp.mailgun.org [54.69.10.167] X=TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 CV=yes DN="C=US,ST=California,L=San Francisco,O=MAILGUN TECHNOLOGIES\, INC,OU=MAILGUN TECHNOLOGIES\, INC,CN=*.mailgun.org" A=plain C="250 Great success" 2018-10-19 14:58:42 1gDWEc-0004Wz-R1 Completed ``` 2. is my understanding correct in reading these logs that there is nothing here about an autoresponse?

MM3 vs. Sympa
by Tom Browder Oct. 21, 2018

Oct. 21, 2018

I still haven’t gotten around to getting a new MM3 service up and running, and now I’m looking at Sympa. I’ve seen a few comparisons of the two systems on the net, but the ones I’ve seen are for announcement lists only. I did see one university that did a study of list managers to replace Listproc and chose Sympa. I must admit my short-lived MM2 experience (used for my social sites for my high school and college classmates) seven years ago wasn’t the best was for two reasons: (1) no duplication of list names even for different domains and (2) it’s written in Python (instead of Perl). But, thanks to much help from Mark, I did get it runnng. I think it would be running today but it failed after about a year when Gmail (whose sntp server I was using) stopped allowing that, and I just didn’t know enough to get around the situation and had too much else to do. I waited expectantly for MM3 to come out and was ready to try again, but the separation of a formerly-integrated system into several systems was a bit daunting. Now I’m considering using Sympa: it’s coded in Perl, it’s monolithic, and it can support identical list names for different domains, so I am leaning in that direction. Before I go, I would appreciate anyone giving me a good reason to stay with MM (besides excellent support and a welcoming community—one which is a member of an unfortunately small group of such communities). Thanks so much. Best regards, -Tom

Difficulties setting up MM3 with Postfix MTA in Docker Environment: Invalid EHLO domain name & Authentification as lists.local
by Niklas Frühauf Oct. 21, 2018

Oct. 21, 2018

Hi everyone, I managed to setup mailman using the maxking/mailman-* docker containers, connected to a postfix/dovecot mailserver and a mysql database. The mail domain is @mail.local, mailman is reachable at lists.local. I can see the mailman UI fine, its connection to the database is working as well, the only things that’s not working is the initial login: When I try to login with the correct credentials of the superuser I added, I get An error occurred while processing your request. To me it seems like mailman is trying to authenticate as “lists.local” or “mail.local” or “localhost” to postfix (which of course isn’t working), then issues a EHLO/HELO to postfix which is not a FQDN. So I guess the latter issue could be resolved by providing a FQDN by mailman. These are the logfiles from the period: mail | Oct 21 11:15:07 mail postfix/postscreen[1862]: CONNECT from [172.18.18.8]:49288 to [172.18.18.254]:25 ldap_1 | 5bcc5fc1 conn=1000 fd=12 ACCEPT from IP=172.18.19.8:49252 (IP=0.0.0.0:389) ldap_1 | 5bcc5fc1 conn=1000 op=0 BIND dn="cn=admin,dc=..." method=128 ldap_1 | 5bcc5fc1 conn=1000 op=0 BIND dn="cn=admin,dc=..." mech=SIMPLE ssf=0 ldap_1 | 5bcc5fc1 conn=1000 op=0 RESULT tag=97 err=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=1 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(mail=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=1 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=1 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=2 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(?mailGroupMember=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=2 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=2 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=3 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(|(mail=*@lists.local)(mailalias=*@lists.local))" ldap_1 | 5bcc5fc1 conn=1000 op=3 SRCH attr=mail ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mail) not indexed ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mailalias) not indexed ldap_1 | 5bcc5fc1 conn=1000 op=3 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=4 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(mail=mail.local)" ldap_1 | 5bcc5fc1 conn=1000 op=4 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=4 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=5 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(?mailGroupMember=mail.local)" ldap_1 | 5bcc5fc1 conn=1000 op=5 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=5 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=6 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(|(mail=*@mail.local)(mailalias=*@mail.local))" ldap_1 | 5bcc5fc1 conn=1000 op=6 SRCH attr=mail ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mail) not indexed ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mailalias) not indexed ldap_1 | 5bcc5fc1 conn=1000 op=6 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=7 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(mail=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=7 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=7 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=8 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(?mailGroupMember=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=8 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=8 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=9 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(|(mail=*@lists.local)(mailalias=*@lists.local))" ldap_1 | 5bcc5fc1 conn=1000 op=9 SRCH attr=mail ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mail) not indexed ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mailalias) not indexed ldap_1 | 5bcc5fc1 conn=1000 op=9 SEARCH RESULT tag=101 err=0 nentries=0 text= mail | Oct 21 11:15:13 mail postfix/postscreen[1862]: PASS OLD [172.18.18.8]:49288 mail | Oct 21 11:15:13 mail postfix/smtpd[1873]: connect from srv-docker_mailman-web_1.srv-docker_frontend[172.18.18.8] mail | Oct 21 11:15:17 mail postfix/postscreen[1862]: warning: dnsblog reply timeout 10s for list.dnswl.org mail | Oct 21 11:15:27 mail postfix/dnsblog[1866]: warning: dnsblog_query: lookup error for DNS query 8.18.18.172.list.dnswl.org: Host or domain name not found.

Hello. I am seeing dkim fail in mail that people send to lists /dkim=fail reason="signature verification failed"/ but it is not happening when the list solely sending mail to subscribers (like digest, or subscribe/unsubscribe messages etc). I recently added a new domain to the mailman3. After this I started noticing this issue. Any help ?

Change digest frequency and default threshold
by Henrik Rasmussen Oct. 12, 2018

Oct. 12, 2018

When creating a new list in Mailman 3, the Digest Size Threshold is set to 30KB, which is not much in my opnion. 1) How do I set another default for Digest Size Threshold for new lists. 2) How do I change the default for existing lists When Digest Size Threshold is not reached, mails seems to be sent according to digest_volume_frequency': which is set to 'monthly'. The web interface doesn't seem to have a setting for this. How do I change this setting, both on a single list and the default for new lists? Henrik Rasmussen

Can't remove footer(s)
by Henrik Rasmussen Oct. 11, 2018

Oct. 11, 2018

I have a problem removing the footer(s) from a list imported from MM2.1. I have been testing by entering my message in Hyperkitty (the list forum). I an aware about the double footer issue[1], and I am aware that footers are cached, but I have removed the footer files according to [2], run Mailman shell according to [3], restarted the Mailman (Mailman core, Mailan web, Postgres database and postfix). Did I miss something in order to remove the footers?
