Mailman 3 Ready?
by Allan Hansen 27 Nov '19

27 Nov '19

Dear all happy campers, I need to upgrade from Mailman 2.1 - my hardware needs upgrading (badly) and the address mangling is having my subscribers rip their hair out. I need to get this done before they start on my already thinning hair! I’m ready and eager to move on to MM3 on a Linux box. First I tried to install it myself. After all, I had installed MM2 and it worked fine until AOL and Yahoo messed it up, My computer (an iMac) presents with a black screen on startup and is apt to die at any moment. I ran into trouble some 4/5 through the installation - I simply got lost in jingo. I then hired a pro, but he had real-life issues that kept him distracted and he also had trouble with the installation. I switched to a second pro, a friend, who has tried valiantly for a few months (on and off) but has basically given up now. This is his latest comment on his efforts after I (gently) nagged him: ************************************* Hi Allan, I have looked into it a few times now and I keep running into the same blocks. I don't see much moving either. I was hoping someone (Mailman developing community) would come up with a better working solution. My concern is that the Mailman3 is not ready. There are too many dead ends and undocumented stuff. For Mailman2 I have a working integration with iRedMail, that does not seem to work with 3. So far I don't have anyone who knows how to make Mailman3 work integrated with iRedMail (or similar). Things I have tried and documented are not a conclusive working installation. ************************************** So, is MM3 ready for the big screen? If so, is there some way/how/where/when that my friend can get help helping me with the installation other than the published installation docs, which did not work for us? I have looked for both free and commercial alternatives to MM, but, frankly, I don’t think that there is anything that comes close to what we have. One of my lists started out on LISTSERV many decades ago. I moved it to Appls’s list server and then I moved it to MM after Apple starting with OS/X. Apparently LISTSERV is still around and is being updated, but I’m not keen on going back there, and it’s very expensive too boot. Any help with this is greatly appreciated! Yours, Allan Hansen

Edit automated responses
by Christian F Buser 23 Nov '19

Hi all I have a list which uses Mailman 2.1.27 running on cPanel 78.0.44. The list has a size limit for the contributions (max_message_size). When a user sends a message which exceeds the limit, he receives a message that his contribution will either need approval of a moderator or be deleted. Can this message be edited so that the user is informed that his contribution is deleted (so not to mention the possibility of a moderator approval)? And is it possible to "auto-delete" contributions exceeding the size limit - without the interaction of a moderator? Thank you, Christian -- Christian F.

Massive amounts of bounces after setting munge_from for dmarc compliance
by Andy Cravens 21 Nov '19

21 Nov '19

Mailman 2.1.26. I modified all our lists that did not have munge_from set for DMARC compliance. I ran a few tests and was able to send and receive email from my test list. Now I’m getting reports that large numbers of emails are bouncing and members are being unsubscribed. I had someone forward a bounce message to me and it says it was rejected because it was suspected as spam. In this sample email the headers show the original sender has some DKIM headers and I do not have mailman set to remove DKIM headers. From the docs I found on the mailman wiki it said to not remove the DKIM headers. This particular list server is on a domain that does not use DKIM but does have an SPF record set to soft fail and the DMARC is set to p=none for monitoring only. The headers in the sample email shows “dkim=fail (signature did not verify)” so I’m thinking I may need to have mailman strip out the DKIM headers from the original sender. Before I modified this particular list I created a test list and added some members from one particular organization. The test list worked fine even though the original DKIM signatures were not removed. I also found this post where this guy says you need to remove the DKIM headers: https://blog.dogan.ch/2016/11/24/making-mailman-dmarc-compatible/

OutgoingRunner processes hanging
by Kevin Bowen 15 Nov '19

15 Nov '19

Hello, Occasionally my mailman instance (2.1.9) gets into a weird state where one or more of its OutgoingRunner processes appears to hang (usually on a large email with a large number of recipients), causing a backlog of all other mail on that process's "shard" (or whatever the terminology is for how mailman divides up mail between runners based on hash). When it gets into this state, doing a mailman restart doesn't manage to successfully kill the "hung" process - it stays around after the restart (along with the mailmanctl instance that started it). Doing a tcpdump on the process usually shows that it's still sending data, but at a trickle (or sometimes not). Any ideas what could cause this, or how to resolve it?

LDAP routing
by Zinski, Steve 15 Nov '19

15 Nov '19

I hope that someone here can help me (or point me in the right direction). We are migrating from sendmail (virtuser) mail routing to LDAP routing. Setting up routing for users is pretty straightforward using the inetLocalMailRecipient class and the mail/mailLocalAddress/mailRoutingAddress attributes. But I was wondering what would be the best (correct) way to represent the mailman alias addresses in LDAP (i.e., list-admin, list-bounces, list-confirm, etc.). Would each get its own entry in LDAP or is there a better way? Any help would be appreciated. Steve [University of Richmond] Steven C.

Munge-from "From:" addresses and address auto-complete
by Dan Halbert 15 Nov '19

15 Nov '19

We have a number of Mailman V2 lists with "Munge-from" turned on, due to DMARC issues at receiving mail systems. This rewrites the From: addresses to something like: From: Dan Halbert via SOME-LIST <SOME-LIST(a)example.org> The problem is some email clients (I'm not sure which ones) pick up these "From:" addresses and add them automatically to the user's address book. Then, when the user wants to send a private (not list) message to some person on the mailing list, they start typing the person's name, and the email client may autocomplete with the list address, not the person's address. If the sender doesn't check the address carefully, they may send to the list inadvertently. This has led to several mildly embarrassing private messages being sent to a list. Is there some configuration I can set up that can alter these "From:" addresses to avoid putting the person's name first, but still including it? Or is there some other way to ameliorate this problem? We could choose something other than "Munge-from", but we do not want to lose the identity of the sender, which is worse. We are using a third-party provider and have no direct control over the formatting of the rewritten "From:" header; I would change the Mailman code directly if I could. Thanks, Dan

Regexp matching failing for accept_these_nonmembers
by Gretchen M Beck 08 Nov '19

08 Nov '19

Hi Folks, I'm on mailman 2.1.18-1, and this week I've received several complaints about messages held for moderation. Specifically, users whose addresses are in the "accept_these_nonmembers" list, or whose addresses match a regexp that is on the list are getting held as "Post by non-member to a members-only list" While I have had one complaint about this happening for a non-umbrella list, most of the examples have the non-member posting to an umbrella list where they are also accept_these_nonmembers, having the message pass through without moderation, then have it held at the next lists down (where it also should be accepted). I thought "well, let's see what parseaddr is returning" and so slapped a syslog at the appropriate point in Moderate.py, but so far what that is showing me matches the regexp in accept_these_nonmembers. What am I missing here? Thanks! --Gretchen Gretchen Beck Carnegie Mellon

confirm.py not working with https
by jimwest＠attglobal.net 05 Nov '19

05 Nov '19

Hi, I have mailman 2.1.12 installed on Centos 6.5 using Apache 2.2.15 and python 2.6.6. The mailman web page "Confirm Subscription Request" generated by confirm.py works fine with http, but does not work with https. In /etc/httpd/httpd.conf, I am redirecting all http traffic to https using the redirect command in httpd.conf. This may be causing a problem in confirm.py when retrieving the confirmation cookie from the URL using cgidata.getvalue. Entering the confirmation cookie manually in confirm.py also does not work. Please let me know if there is a modification that I can make for confirm.py to work with https. To make my website more secure, my website is configured to only work with https and not with http. Please let me know how I can use confirm.py with https. confirm.py works fine with http, but not with https. Your help with this problem is appreciated. Thanks, Jim West

Mailman Python Apache CGI issue
by jimwest＠attglobal.net 05 Nov '19

05 Nov '19

I am new to Mailman, and have just installed Mailman 2.1.12-26 on a Centos 6.5 server. My httpd version is 2.2.15 My python version is python-2.6.6-51. Everything appears to be working fine, except when a new subscriber confirms there subscription request. The email from Mailman gives the user the option of confirming their subscription by going to the confirm web page. Confirming the subscription using the email method works fine, but the web page confirmation is having problems. For a user named "dot" joining the Skipper group, the URL is: http://<my-web-site>/mailman/confirm/skipper/b36adbfa6d4b9af927197b75006444262696b9a6 <http://kjm.PositionDatabase.com/mailman/confirm/skipper/b36adbfa6d4b9af9271…> The string "b36adbfa6d4b9af927197b75006444262696b9a6" <http://kjm.PositionDatabase.com/mailman/confirm/skipper/b36adbfa6d4b9af9271…> is the confirmation "cookie". After the user clicks to subscribe to the group on the Confirm Subscription web page, the confirm.py script checks to see if the cookie was entered in the URL: # Get the form data to see if this is a second-step confirmation cgidata = cgi.FieldStorage(keep_blank_values=1) cookie = cgidata.getvalue('cookie') if cookie == '': ask_for_cookie(mlist, doc, _('Confirmation string was empty.')) return In my installation, the cdigdata.getvalue is not returning the cookie entered in the URL, so the "Enter Confirmation Cookie" web page is called ... even though the cookie was included in the URL. If the user enters the "cookie" again in the "Confirmation String" window, the user clicking "submit" does nothing. It appears that I have a configuration problem in my Apache or Python interface. I am not seeing any errors in /var/log/mailman/error log. My /etc/httpd/conf.d/mailman.conf file is not generating any errors in /etc/httpd/error_log, and The redirect for "/mailman" appears to be working, since my mailman url is working. From the confirm.py script, it appears the "cookie" should have been obtained from the URL, and there should have been no need to call the "Enter Confirmation Cookie" to have the user enter the cookie again... and as luck would have it, the Enter Confirmation Cookie web page is also not working. This is definitely a new user configuration problem, and I would appreciate any suggestions for how to fix this problem. Thanks, Jim West Email: jimwest(a)attglobal.net
