Hotmail porn spam

[Johnny Stork]

I have seen a significant increase in porn spam coming from mostly 
hotmail accounts and it is getting through 3 different spam detection 
systems right now!!


I run ASSP on my remote server, then mail is pushed through mailscanner, 
and then through Astaro Secure Gateway!!! How is this possible?

Anyway, is there something I can post here that might help in trying to 
find a solution (other than blocking all hotmail messages)

I am reluctant to post the entire header since there is a great deal of 
identifying info on my servers.

Ideas?
