Upgrade categorizes formerly legit email as junk

Maintenance
1

When I upgraded my MIAB to 0.53, legit email is now being flagged as junk. What is going on? I’ve made no other changes to the box beyond ubuntu updates.

Thanks!

Please post the X-Spam-Report header section of an email going to your spam folder.

Is this, by chance, a message generated by a list of some sort?

yes, a mailing list. most, if not all, my mailing list incoming mails are now being marked as junk. individual emails at first glance appear to be getting through fine.

This changed in 0.52 which may be upping the spam score?

  • Incoming emails with SPF/DKIM/DMARC failures now get a higher spam score, and these messages are more likely to appear in the junk folder, since they are often spam/phishing.

If so, may worth searching forum for that topic.

At this point the only solution I’m able to recommend is to create custom file for spamassassin.

$ sudo nano /etc/spamassassin/yourcustomfilename.cf

Add to the newly created file the address used by the mailing list:

whitelist_from username@example.com

This adds -100 to the score so basically everything from that address will always arrive in the inbox.

Then restart all the stuffs:

$ sudo service spampd restart
$ sudo service spamassassin restart
$ sudo service postfix restart

Thank you Openletter. question: can I add additional lines in yourcustomfilename.cf to whitelist other senders like this?

whitelist_from username@example.com
whitelist_from username@boop.com
whitelist_from username@whatever.com

Yes, you can add as many lines as you like. IIRC, spamassassin evaluates everything line-by-line.

Here is the documentation on this feature and several other useful ones:

@christian7

May I also suggest opening an issue on Github to make the devs aware that their spam assassin changes may be too restrictive?

However, in the case of the specific email that you shared the headers for, your comments should be directed towards the maintainers of the list for they have several configuration errors that they really should fix.

Thank you all for your suggestions and guidance!
