Description Kenneth Porter 2020-02-23 19:44:27 UTC 
Facebook's mail is caught by __HELO_DYNAMIC_IPADDR2. A typical sending server is 66-220-155-140.mail-mail.facebook.com.

Workaround is to add /etc/mail/spamassassin/facebook.cf with content:

header __HELO_DYNAMIC_IPADDR2 X-Spam-Relays-External =~ /^[^\]]+ helo=(?![^\s\]]+[-.](static|mail-mail)[-.])\d{1,3}(?:[\Wx_]\d{1,3}){3}[^\d\s][^\s.]*\.\S+\.\S+[^\]]+ auth= /i

Comment 2 Henrik Krohns 2020-04-10 08:02:13 UTC 
Added some basic exclusions. All these dynamic rules could use much love..
