spamming
by Jim Dory 09 Aug '24

09 Aug '24

I've got a new problem with my mailing list. I run a local announcements/trade list that should be of no interest to non-locals. I started seeing warnings from Yahoo about users marking messages as spam.. (I'm subscribed to Yahoo's Antispam Feedback. I never got other feedback loops from others - like Microsoft - to work). The messages that were being marked as spam by users were the confirmation emails sent by mailman to confirm a signup. To avoid having Yahoo shut down the list as spam (for its subscribers), I set the subscription to be approved by admin, so I could review who was trying to sign up. More and more now I'm seeing what appears to be spammers trying to subscribe, but I can't be sure. I'm seeing emails like: hirofeet0916(a)yahoo.co.jp (doesn't seem local) blvckpvlm(a)gmail.com (not many use user names such as that) fsafwcasgsadf2(a)gwqc.com (obviously not real - couldn't find domain with minimal searching) Plus some that could be local but how would I know. I could take off the "approval by admin" for subscription and just deal with anyone that is a problem afterward, but I do worry that they may be harvesting emails from subscribers, which are available in the reply-to headers. Don't know if there's anything I can do. Anyone else dealing with this? thanks. Jim

Editing Mailman's text files
by Pete Bell 07 May '24

07 May '24

Hi. I'm a new member of this group but have been running an email list with Mailman for a long time. I am now setting a list up again and want to give a "look and feel" to the list which has more branding of my user group as a whole, and less of a Mailman-feel. I seem to remember that besides editing the public HTML pages, it is possible to edit the text files which Mailman automatically sends out for certain needs (such as 'approve.txt', 'adminsubscribeack.txt', 'invite.txt', and so on). A. Is this still the case? B. If so, where can I find them? (in case they've changed from the ones I have from long ago). C. Where do they need putting, so that Mailman can use them again? It's important that I should tell you that Mailman on my webhosts servers is a "server-wide" installation, and I don't get to edit anything which other clients to their servers need. This would be only for my own use, and as such I need to know where these files go in my own webspace, and how to get Mailman to use them instead of the default ones. I should also say that I have done this before, so unless the facility to do this has been ditched in recent years, I *should* still be able to do it ! Does Mailman perhaps look for these files somewhere in my webspace (which I have to give a specific name), and if it doesn't find them it goes on to find its default versions of these files? Thanks in advance for your help. Pete Bell, UK

Cloudmark blacklist
by Jayson Smith 17 Apr '24

17 Apr '24

Hi, I run two very low traffic Mailman lists on my Linode. This morning one of them got an Email, and that's when I found out thanks to Comcast that my IP is on Cloudmark's blacklist. Naturally I've sent in a reset request using the form linked from the Comcast error message, and am still waiting to be removed. A few days ago I sent to a Comcast customer with no problem. I've resolved the problem sending to Comcast by enabling my server to send using IPv6. This required me to have Linode allocate me my own /64 since my default IPv6 address was in a /64 blocked by Spamhaus XBL/CSS lists. Does anyone know if Cloudmark blocks entire IP ranges or just individual addresses? I don't know why my IP is on Cloudmark's list, as most of the Email I send is personal in nature, to people I have corresponded with for years. I've used multiple RBL check tools, and everything has come back negative, except that my entire subnet is on Spamgrouper.to (checked by running a check on a neighboring IP). I have SPF, DKIM, and DMARC set up. I'm getting really tired of these unexplained blacklistings. Does anyone know of any reliable outgoing Email service providers? Ideally I want to continue to handle my own incoming Email because I don't want someone else's spam blocking software deciding what Emails I receive. Thanks, Jayson

by Ralf Hildebrandt 15 Apr '24

15 Apr '24

Using mailman-2.6.x: Is it possible to create a list (via CLI or the WUI) which has multiple owner addresses? Why? ==== Often my users want lists with multiple owners, and so I need a way of EITHER: * creating the list with multiple owners, all of which are getting the "Your list has been created"-email OR * re-sending the "Your list has been created"-Email after I manually added the extra owners Enlighten me! -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Error member gets when sending to one of my lists?
by Adam Morris 18 Mar '24

18 Mar '24

Hi all, A member is subscribed to two lists I run. He can post to one but gets the following error when posting to the other list. I don’t think I have things set differently for any of the lists I run. SMTP error from remote mail server after end of data: 550 Maximum line length exceeded (see RFC 5322 2.1.1). TIA.

Outlook blocked again, but strange response
by Jayson Smith 16 Mar '24

16 Mar '24

Hi, So it's happened again and I have no idea why, though I suspect some of my IP neighbors may have been put on Microsoft's naughty list as my subnet with Linode was recently listed on Uceprotect level 2. Anyway, I go to send an Email to an Outlook user, and get the typical thing, Unfortunately, messages from XXX.XXX.XXX.XXX weren't sent. Fill out the support request, expect to get conditionally mitigated in a few hours…nope. Instead, I get this: Hi , Thanks for your patience, we are currently experiencing technical difficulties and our engineers are working to resolve the issue at the earliest. Thanks again, Outlook.com Deliverability Support Has anyone received this from Microsoft before? If so, will the issue eventually be resolved, or do I need to wait a few days and submit my request again? Thanks, Jayson

mailman httpd location question
by Mark 10 Mar '24

10 Mar '24

Hi, Under OpenBSD's httpd, my mailman setup gives an HTTP 404 error when 'mysite.com/listinfo' is typed, however 'mysite.com/listinfo/' works. In order to *solve* this issue, I added 2 different locations pointing to the same cgi script, as: location "/listinfo" { fastcgi socket "/var/www/run/slowcgi.sock" root "/usr/local/lib/mailman/cgi-bin/listinfo" request strip 1 } location "/listinfo/*" { fastcgi socket "/var/www/run/slowcgi.sock" root "/usr/local/lib/mailman/cgi-bin/listinfo" request strip 1 } The same goes for /create and other cgi scripts as well. Wondering how to make both ways (with ending '/' and without) work? Is there any parameter configuring this in mailman2? Best wishes, Mark.

Digest not being received in a timely fashion
by jan＠janalexander.ca 08 Mar '24

08 Mar '24

For years our digest has arrived at 9:00 am (PST). In the last six months it has been erratic, arriving at different times during the day. Now, recently it is not arriving for a day, sometimes days. It's pretty useless to our members to have messages from one or two days ago arrive late. I've asked the Mailman hosting company about this repeatedly. Their answer is that bigger volume mailist senders on shared servers take time in the queue, and our little mailist has to wait until their messages are processed. They've asked them to move to a dedicated server, but the delays are still occurring. I've asked them about setting up a Cron job to schedule the release of our emails, but haven't received a definitive answer. Anyone have any suggestions?

Apple and Microsoft emails bounced
by jan＠janalexander.ca 08 Mar '24

08 Mar '24

Routinely, email posts from Microsoft (.hotmail, .live, .me) and now more recently Apple (.icloud and .mac) are being bounced en masse. Is there something we or our host can do to stop this from happening? Appreciate any advice. Thanks

Non-delivery of approved messages
by Francis Jayakanth 03 Mar '24

03 Mar '24

Hi, I administer and moderate a library and information science professional list. The list is running on Mailman 2.1.26. There are nearly 5k list subscribers, of which almost 4k are 'digest' registrants. The majority of the registrations are with personal email IDs. During the last couple of weeks, approved messages are not being delivered to the list members. When I check the Email & collaboration alerts in the Microsoft 365 Admin Portal, I see the following message: Suspicious email sending patterns detected, User was restricted from sending emails. Additionally, a pop-up on the screen reads: "Unblock entities which have been blocked for sending too many messages marked as spam/bulk." The first approved message gets delivered after unblocking the relevant email ID and approving another message after 24 hours. For the subsequent one, the emails bounced back, and the MS admin portal reported the same error messages mentioned above. Can someone please help me fix this issue? Thank you for your attention and time, Francis
