I see more and more users complaining about a typical SPAM activity that occurs since early December. I'm very surprised that these messages are successful at defeating numerous anti-SPAM techniques used on our Zimbra server. RBLs are enabled, SpamAssassin too as well as Greylisting. The SPAM comes from domains with good reputation.
My first question is : Anyone else is seeing this? Am I under a targeted attack?
My second question is: Anyone having a suggestion so we could tweak SpamAssassin to increase the spam score for these messages?
Thanks in advance!
Here is the typical SPAM message we receive :
