Postings being discarded due to DKIM failures?
by Robert Heller 15 May '14

15 May '14

A list member recently tried to post a message to a list and the message was discarded for no *appearent* reason. The only clue is that for some reason the message is failing the DKIM check (DKIM=fail). I am using Mailman 2.1.16 on CentOS 5 (python-2.4.3-56.el5, httpd-2.2.3-85.el5.centos, dkim-milter-2.8.3-8.el5). Is there some way to get Mailman to log why it is discarding messages? -- Robert Heller -- 978-544-6933 / heller(a)deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments

Get newer version of Mailman for Debian 6?
by Sascha Rissel 15 May '14

15 May '14

Hello there, I am running a vServer on Debian6. Via "apt-get install mailman" I installed and set up Mailman 2.1.13, which is running fine with 5 mailing lists on my server. Motivated by all those discussions about Yahoo's DMARC on this list, I wondered whether I can upgrade my Mailman installation to a newer version. I tried "apt-get update" and "apt-get upgrade" but I did not receive a newer version of Mailman. Unfortunately I don't consider myself as good enough in Linux usage, to be able to build Mailman binaries from scratch on my own. Indeed I tried, but already upon executing "configure" (Step 3 in Mailman's installation guide<http://list.org/mailman-install/node7.html>) I got a python warning > Distutils is not available or is incomplete which seems to tell me I should install another Python environment. So I came to the point when I decided that compiling Mailman on my own is too complicated for me, because in the end I definitely want a bug-free installation of Mailman. Is there maybe an easier way to get a more recent version of Mailman for my server? In advance, thanks for your help! Sascha.

mailman-AttachmentMove: completely remove moved attachment?
by Sylvain Viart 15 May '14

15 May '14

Hi, What'd be the trouble if I completely remove attachment from the message? First I've copied the behavior of the Handler Scrubber.py and ThunderBird filelink module. It wipes the attachment but sill send a fake one. Which looks like: --------------020101070601020108020001 X-Mozilla-Cloud-Part: cloudFile; url=http://remotelocation/remotefile; name=original_name.pdf Content-Type: application/octet-stream Content-Transfer-Encoding: 7bit Regards, Sylvain

Re: [Mailman-Users] Virtual Mailman broke!

It's been a problem forever, but I've forgotten the magic fixes to magic files that I've done in the past to correct it. Thanks for your patient questions, Mark. When I said I'd been there before, I realized I should search the mailman-users list archive, and there it was! I used the mailman web form to create the new list, and the initial symptom is that email to that new address bounces with "address unknown" error. After manually adding the new list to /var/mailman/data "aliases" and "virtual-mailman" to look like the other functioning lists, I ran "postmap virtual-mailman" and "newaliases". When I went searching through archives for virtual mailman problems and my name, I found a posting that said I needed to run "postalias aliases" in that directory. I did so, and now all is well. Yes, Apple's implementation appears to be badly broken. I'm saving this email as text in the /var/mailman/data directory and the /etc/postfix directories, to save myself some pain the next time it happens... :-) :::: Jan Steinman, EcoReality Co-op ::::

Virtual Mailman broke!
by Jan Steinman 15 May '14

15 May '14

I'm using the Mailman and postfix that came bundled with MacOS X 10.6 (Snow Leopard) on a Mac Mini Server. I have problems adding new lists using the web interface. It's been a problem forever, but I've forgotten the magic fixes to magic files that I've done in the past to correct it. I have a number of small non-profits that I host websites for, and each has one or more Mailman lists. I run my own DNS and MTA using the domain "bytesmiths.com". All these virtual domain lists were working, until I added a new list to one of them. It failed to accept the new mailman list address after adding the new list through the Mailman web interface. So then I started poking around, and noticed the new list did not appear like other functioning lists in /var/mailman/data files. I carefully added the new list by editing "aliases" and "virtual-mailman" files that warned ominously "do not edit!" and ran newaliases(1). I verified that the .db files are newer than the edited text files. Well, now NONE of my virtual domains work any more. They fail by redirecting to the base domain. For example, mail to new list "glarp(a)VirtualDomain.org" -- previously working -- fails with a bounce that "glarp(a)bytesmiths.com" doesn't exist. Rather than deluge you with config files and error logs, I thought I'd post the symptoms first, to see if anyone could point me in the right direction, or could request specific config/log info. My gratis "customers" are being very understanding, given the vast amounts they are paying me, but needless to say, I'd like to get them back up ASAP! Does anyone know what's going on, and how to fix it? What additional information can I provide? Thanks in advance for any advice offered! :::: No, Plaintiffs to not have a fundamental right to own and use a dairy cow or a dairy herd...

Subscription flood
by Bill Christensen 15 May '14

15 May '14

Hi all, I've got a problem with one of my lists where it's being flooded with spurious subscription requests. The list was set to require subscription confirmation; the innocent victims whose addresses were used for the subscription requests started complaining, as they'd get anywhere from 2 to 400 (!) confirmation requests in a day from a list they'd never even heard of. About 12 hrs ago I switched it to require Admin approval. 500+ subscription requests - mostly in batches of 5-10 from the same address - have come through since then. I attempted requiring both confirmation and admin approval, but the order of operations is that the admin isn't asked to approve until a confirmation comes through. That's no help to the victims receiving the confirm requests. Question 1: Is it possible to reverse the order of approval and confirmation when requiring both? The admin then can reject all those with duplicates, only allowing the (presumably real) single subscription requests to send out a confirmation request. If so, how would that be done? Question 2: Any other suggestions on how to handle this? Currently running mailman 2.1.13_0 (Next stop is to MacPorts list to see if the maintainer will update the port to the latest version)

> I've got a problem with one of my lists where it's being flooded with spurious subscription requests... from the same address... Perhaps obvious, and perhaps in the FAQ Mark linked, but this sounds like a job for ipfw to me. I regularly get spambot subscription requests, and they go right in the firewall. (For example: "ipfw add deny tcp from 1.2.3.4 to any". You could add port 25, but I figure if they are so lax to allow email list spambots, I don't need to listen to them at all.) Generally, they're from countries I could care less about, but if they come from someplace "civilized," I may let their abuse address know. (Found via "whois 1.2.3.4", for example.) :::: Half a man's wisdom goes with his courage. -- Ralph Waldo Emerson :::: Jan Steinman, EcoReality Co-op ::::

A word to the wise: spam-checking and RFC conformance
by Stephen J. Turnbull 14 May '14

14 May '14

Hi all, I just discovered that the spam-checker for a non-Mailman list I subscribe to (I suspect SpamAssassin but I can't confirm yet, the MLM is ListServ) is introducing 8-bit characters into the header. What appears to be happening is that the original post uses a Content-Transfer-Encoding of 8bit or binary, and contains some 8-bit octets (typically fancy quotes and the occasional accented character in the posts I receive), and the spam checker copies an excerpt from the body into the "X-Spam-Report" field *verbatim*, including the non-ASCII characters. If your spam-checker doesn't produce an "X-Spam-Report" field or similar, you don't have the problem. If it does, you might want to check its behavior with respect to body excerpts. Regards, Steve

2.1.18-1 - this is new

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
