Issue with receiving mail from Facebook

Post by MauriceW » 27 Jul 2015 17:25

I'm experiencing a strange issue with receiving mail from Facebook.

I'm running a home server and have the mx records for my domain pointing to it. As a backup I use the mail service from DNSMadeEasy (lower priority mx records pointing to their server).

Since a few weeks, the Facebook mail server (mx-out.facebook.com) does not want to deliver mail to my primary mx record anymore, because all the Facebook notification messages are coming in from the DNSMadeEasy servers.

Unfortunately this also means that all Facebook notifications are being marked as spam because of "KAM_FACEBOOKMAIL - Fake or Abused Facebook Mail" which adds 8.00 to the spam score.

Any clues as to why Facebook won't deliver mail to my primary mx record anymore? And is it possible to disable the KAM_FACEBOOKMAIL rule as a workaround?

Yes, you can add an exception to /etc/mail/spamassassin/local.cf

Basically, create a rule KAM_FACEBOOKMAIL and set the score to 0
