DMARC and Reply-To lines with from_is_list munging.
by Glenn Sieb 13 May '14

13 May '14

Greetings... So I run a bunch of mailing lists, with a bunch of people who are not technically adept whatsoever. ("I am not getting list posts! "That's because you set yourself to no mail" "What's no mail?" "It means you set yourself to be a member of the list, but not to get any email from it." "Oh that's good." "So we're good then?" "But why am I not getting any emails from the list?" *headdesk*--yes this was an actual conversation with a user.) People are, of course, bitching about the from_is_list setting removing the email addresses of people who are sending email to the lists. (And people aren't quite understanding that it's helpful to sign one's emails, etc. So I updated to 2.1.18-1 today. Now we have a Reply-To that has the poster's email and the list's email address. A few of the lists I run block emails with more than one recipient, so now this is going to be an adventure. (Ok, more like a nightmare, as right now it appears my choices are "make reply-to only the list" ("anonymous_list") or "make reply-to the poster and the list.") I wonder if this solution might be more helpful here--something like what Google Groups is doing. Changing the From line to this: 'First Last <firstlast(a)domain.com>' via List Title <list-address(a)googlegroups.com> This still shows the poster's email address (as the Real Name), which makes it easier for people to reply privately if they choose, and still addresses the DMARC issue. Thoughts? Ideas? Best, --Glenn

Logging fail?
by Mark J Bradakis 13 May '14

13 May '14

So I update to the latest 2.1.18. Mailman quits working. Sure, all the qrunners are running, but any mail to any list just disappears. Postfix gets it and sends it on: May 11 19:09:51 autox postfix/local[22287]: 2A5C32D60BBD: to=<tn_admin(a)autox.team.net>, relay=local, delay=0.13, delays=0.01/0/0/0.13, dsn=2.0.0, status=sent (delivered to command: /local/mailman/teamnet/mail/mailman post tn_admin) Go to the logs directory, grep for 'tn_admin' and nothing shows up. Where did the message go? Why is it not getting sent to the list? Why is there no trace of it in any logs? mjb.

Saving list subscribers from a backup
by Bernie Cosell 13 May '14

13 May '14

in the face of zillions of bounce/unsubscribes thanks to the DMARC mess, what I'd like to do is get the sysadmin to snapshot the list members from, say, a week ago. Then when we get things cleaned up I can 'restore' the list as it was. I don't know how to do it and I tried googling and only found: https://mail.python.org/pipermail/mailman-users/2003-March/027011.html which said ~/mailman/lists/<list_name>/config.db On our system, though, all I find is: mailman$ ls Mailman/ archive/ bin/ cgi-bin/ cron/ icons/ mail/ messages/ pythonlib/ scripts/ templates/ tests/ so no "lists" diretory at all. Obviously that's for a very old version of mailman We have: Using Mailman version: 2.1.9 Thanks /b\ -- Bernie Cosell Fantasy Farm Fibers mailto:bernie@fantasyfarm.com Pearisburg, VA --> Too many people, too few sheep <--

MM 2.1.18-1 question
by Lindsay Haisley 13 May '14

13 May '14

My understanding is that MM 2.1.18-1 corrects a python version incompatibility in MM 2.1.18 and nothing more. My MM server is running python 2.7.3 and I've had no problems with MM 2.1.18. Are there any compelling reasons for me to upgrade? I have a patch collection which would need to be re-applied, a bit of a PITA but I can do it if necessary. -- Lindsay Haisley | "Everything works if you let it" FMP Computer Services | 512-259-1190 | - The Roadie http://www.fmp.com |

Results of testing posts to yahoogroups from AOL
by Mark Sapiro 12 May '14

12 May '14

I finally got around to testing this. I posted three times to my test Yahoo group from 'Mark Sapiro <my_aol_address(a)aol.com>'. One post with the group set to send replies to the group and one post with the group set to send replies to the sender and one post with the group set to send replies to the sender and the group. In all cases, the posts were sent with From: "Mark Sapiro my_aol_address(a)aol.com [my_yahoo_groupname]" <my_yahoo_groupname(a)yahoogroups.com> In the first case (replies to group), there was Reply-To: <my_yahoo_groupname(a)yahoogroups.com> in the post from the group. This seems correct, and my actual address was in the display name portion of From: In the second case, there was no Reply-To: in the message meaning a simple 'reply' was addressed to the From: address which I suppose is fairly easy to edit to go to me, but without editing, 'reply' goes to the group which is wrong. In the third (reply to both) case there is a Reply-To: my_yahoo_groupname(a)yahoogroups.com,Mark Sapiro <my_aol_address(a)aol.com> which is correct. So the bottom line is Yahoo groups does From: header munging when necessary because of DMARC policies on the From: domain and they manage Reply-To: well in two cases out of three. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

MM-2.1.15: Small bug regarding the "request forgery check"
by Ralf Hildebrandt 12 May '14

12 May '14

Today I check the subscribers list ("Membership Management... Section") on one of our lists and called up the legend using "Click here to include the legend for this table." After clicking on that link, the page did indeed display the legend, but the page now starts with: Error: The form lifetime has expired.

Yahoo forced browser update?
by Lindsay Haisley 12 May '14

Does anyone know anything about this? And are there any connections between this forced browser update and Yahoo's DMARC implementation? http://yahoomail.tumblr.com/post/85155936276/an-update-to-yahoo-mails-suppo… -- Lindsay Haisley | "Everything works if you let it" FMP Computer Services | 512-259-1190 | - The Roadie http://www.fmp.com |

Private Archives Aren't Private
by Kevin Monceaux 09 May '14

09 May '14

Fellow Mailman Users, I'm considering switching from Ecartis to Mailman to use some of Mailman's new features for dealing with DMARC. I have 2.1.18 installed via FreeBSD ports and have set up a test list. The list archives are set to private. When I visit the list info page it displays (The current archive is only available to the list members.) next to the archive link, but I can click the link and view the archives without being prompted to log in first. I'm probably overlooking something simple. -- Kevin http://www.RawFedDogs.net http://Lassie.RawFedDogs.net http://www.WacoAgilityGroup.org Bruceville, TX What's the definition of a legacy system?

Can Someone Explain This?

I am recently having trouble posting messages to Ibiblio from my AT&T mail account. There have been issues lately with AOL and Yahoo changing their headers, but I was not affected by this. My email postings to Ibiblio are being rejected with the following error: This is the mail system at host lists.ibiblio.org. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.

mailman processor sponge?
by Ecklund, Morgan 08 May '14

08 May '14

Hello Listers, I migrated to a VMware ESXI environment from an old P3/512 MB mailman server (RedHat/sendmail, mailman had been upgraded to 2.1.x (I think)). The new environment is CentoOS 6.2 Postfix Mailman 2.1.16rc2. Anyway the old server was a rock! The new mailman environment is a processor sponge (clearly not an all-natural hand collected sponge either) I will go over the entire process. After quite a bit of work with the migration (mostly because my learning curve with postfix) I got Mailman working. So we noticed right off the bat that Mailman was maxing the processor and filling memory and later I found that it was filling up the hard drive... So I had the ESXI admin add another processor and memory. Fixed the memory problem. Then all the sudden messages stopped going out to lists ( that was when I found out the drive was filling up). I found that the data directory was large, dare I say bloated beyond recognition. Looked like old held messages were filling up the drive (I think from my Postfix testing, maybe). I went in and ran "bin/discard data/heldmsg-mailman-1*" restarted mailman. Seemed to fix the problem. I also noticed there was a owner-bounces.mbox -rw-------. 1 mailman mailman 51198511 May 8 10:25 owner-bounces.mbox The drive filling issue appears to under control now. Further trouble shooting and a report that we were getting bounce reports saying that google was not allowing more message per smtp connection. Led me to add these lines to my mm_cfg.py file. SMTP_MAX_RCPTS = 1 VERP_CONFIRMATIONS = Yes Now the processor is close to 100%. Messages are going out slow. I followed some trouble shooting guides to many to mention. So I put it to you ohh masters of the Mailman universe.. Thanks for any help you can provide. Morgan Ecklund
