diagnosing messages missing from archives
by Matt Morgan 16 May '17

16 May '17

I'm working on a complaint about messages being delivered, but not getting into a private mailman archives. I found a discussion about diagnosing it, from a few years ago, here: http://grokbase.com/t/python/mailman-users/093t4rv1zv/some-messages-missing… This is on a very low activity list, so I can see that the messages are not just threaded unexpectedly (from an edited subj line). I'm not sure I can get the full headers of the message to check for x_no_archive or similar (though I'm trying). I do see this in the error log: Apr 27 20:58:43 2017 (517) Uncaught runner exception: 'ascii' codec can't decode byte 0xb5 in position 26: ordinal not in range(128) Apr 27 20:58:43 2017 (517) Traceback (most recent call last): File "/usr/local/mailman/Mailman/Queue/Runner.py", line 119, in _oneloop self._onefile(msg, msgdata) File "/usr/local/mailman/Mailman/Queue/Runner.py", line 190, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/local/mailman/Mailman/Queue/ArchRunner.py", line 77, in _dispose mlist.ArchiveMail(msg) File "/usr/local/mailman/Mailman/Archiver/Archiver.py", line 216, in ArchiveMail h.processUnixMailbox(f) File "/usr/local/mailman/Mailman/Archiver/pipermail.py", line 596, in processUnixMailbox self.add_article(a) File "/usr/local/mailman/Mailman/Archiver/pipermail.py", line 640, in add_article author = fixAuthor(article.decoded['author']) File "/usr/local/mailman/Mailman/Archiver/pipermail.py", line 63, in fixAuthor while i>0 and (L[i-1][0] in lowercase or UnicodeDecodeError: 'ascii' codec can't decode byte 0xb5 in position 26: ordinal not in range(128) Apr 27 20:58:43 2017 (517) SHUNTING: 1493351921.551243+8e185be2446d37cbda2f99d888a5a7b7e0643d85 Is that the error I'm looking for? That ArchRunner line looks relevant. It's a reasonably common series of entries in the log (10ish times a day), though the timing doesn't line up with the date/time on the messages that are missing. Is that normal? Is there a way to verify that the error is specific to any given missing message? Thanks, Matt

Cannot approve a moderation-held post
by Phil Stracchino 11 May '17

11 May '17

I'm running Mailman 2.1.23 along with Postfix 3.2.0 and Apache 2.4.25. I have a held message from a mailing list member who was (at the user's request) placed on moderation some time ago after a Girl Scouts phone app stole her address book and spammed it. I cannot approve the message. I've tried three different browsers. I've already successfully unmoderated the user, I select "Approve", click Submit All, and I just get dumped straight back at the held-message-approval page with the message still held. I've checked all relevant logs and there are no errors being logged either by Apache, by Postfix, or by Mailman itself. Everything else works except that I cannot approve this held message. "Nothing's wrong, it just doesn't work." I also tried approving by replying to <list>-request with an Approve: <password> command, and that didn't work either. Does anyone have any idea what could be causing this problem, and how I can fix it and prevent future occurrences? Except for simply never using moderation? -- Phil Stracchino Babylon Communications phils(a)caerllewys.net phil(a)co.ordinate.org Landline: 603.293.8485

Message Held for approval -- too verbose
by Piet Barber 11 May '17

11 May '17

Hi. I have a mailing list, and it gets a lot of spam. The spammers have gotten very good at getting through my multiple layers of defense, spam assassin, grey listing, SPF, DKIM, DMARC. I hate the spammers. Of all the difficult things that systems administration handles; it's mail administration I hate the most. And I hate it because of spammers. scumbags. The problem is when the "This message has been held by a moderator for approval" messages come to me. My Gmail is labeling those as spam. They're labeling them as spam because Mailman is forwarding the entire message to my moderator address (hosted on Gmail). I sure can't find any sort of dialog in the archives about how to do this, and i haven't found an option to do what I want. What I want: I want the "there are 2 messages held for approval" type messages from Mailman not to contain the spam. Don't contain anything in the message at all, except the sender and maybe the subject. Instead of repeating all of the spammy content, is there any way to get Mailman to say something like "Hey there's a message, go check it out" The nature of the mailing list must allow for unknown people to contact the mailing list; sometimes somebody we never heard of has to send mail to the mailing list. So a hard-rule white-list won't work. So don't suggest that.

What happens when public_suffix_list.dat can't be loaded?
by Sebastian Hagedorn 11 May '17

11 May '17

Hi, for the moment we are stuck with a buggy version of Python 2.7 that has recently become unable to load the URL <https://publicsuffix.org/list/public_suffix_list.dat> Since the end of April the attempt results in this error message: Unable to retrieve data from https://publicsuffix.org/list/public_suffix_list.dat: <urlopen error [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:661)> Apparently this is caused by the lack of support for SNI in that Python version (python27-2.7.13-1.ius.el5) AFAICT the list is only needed to map domain names to corresponding Organizational Domains in the context of DMARC handling. It looks to me as if that doesn't cause any problems, but I thought I'd ask ...

view all members of a list on one page with names
by Liste Yoneticisi 10 May '17

10 May '17

Hello; List administrators can see the list members on one page with the following link. http://www.example.com/mailman/roster/list-name But this page executes only the members' e-mail addresses. Is it possible to see the full names also. -- Enformatik Grubu - Elektronik Liste Servisi ODTÜ Bilgi İşlem Daire Başkanlığı

Targeted attack against german universities using mailman
by Julian Kippels 10 May '17

10 May '17

Hi all, there seems to be a targeted attack against public mailman lists at german universities at the moment. I have heared from 3 seperate unis having this problem, Regensburg, Münster and us in Düsseldorf. As far as I can see this attack works like this: A mail with envelop-from www-data(a)dreadnoughtpc.com and From:-Header "Jennifer Lankford" <esag-theater-owner(a)uni-duesseldorf.de> is delivered to our list esag-theater(a)uni-duesseldorf.de This list is configured only to accept mails from members and to hold all other mails for the moderators to inspect. The mail is correctly held to be moderated BUT it is also forwarded to all members with From:-Header "Jennifer Lankford" <real.address.of.owner(a)uni-duesseldorf.de> I can't see why or how this could work. What am I missing? We are using Mailman 2.1.15 Thanks in advance Julian

Preventing abusive / malicious subscription requests
by Matthew Blissett 09 May '17

09 May '17

Hi, I administrate two small, public Mailman servers. On one of them [1], I see a lot of unsolicited subscription requests. For example, win**********ad(a)gmail.com was subscribed 41 times last week, from 13 different IP addresses. A whois search on these IP addresses suggests they're from anonymization services or spam-friendly hosting companies. In total, there were 234 requests last week, the vast majority were unwanted. Does anyone have any advice on preventing this abuse? Subscriptions require confirmation from the user, so manual approval won't help -- there's still a notification that the request awaits manual approval. Preventing sign-up from a dodgy IP is one option, perhaps directing users to email the list owner if they have been caught incorrectly -- has anyone set up anything like this? Thanks, Matt Blissett [1] lists.tdwg.org

Mailman moderation via E-mail
by Zalezny Niezalezny 09 May '17

09 May '17

Hi, our Mailman Webpanel is not available for our external partners (its behind firewall and its accesible only from internal environment). Is it possible to moderate an E-mails using only E-mail communication ? Is it possible this kind of scenario to moderate an E-mail using only e-mail communication ? For example: 1. Moderator sending message on list(a)example.com 2. Moderator receiving his own message (with msg file) and needs to send it back to approve it 3. Moderator sending message back to the server (maybe with some command "approved" etc.etc.) 4. Message is accepted by the Mailman server and server starting to send messages to all users. With kind regards Zalezny
