Hello all,

 

I need help to fight against spammers, here is a sample of an smtp log
entry:

 

 

"mail"  "mail"  "72.16.236.115" "2011-07-06 12:46:21"
"ALEXSERVER01.ANDREWALEX.local" "hotmail.co.uk"
"[email protected]""[email protected]"     "SE86331"
"RECV=OK"       "[email protected]"  "2507"  ""

 

 

I am receiving sometimes hundreds of this kind of email in a short time. I
have tried black listing the IP and sender domain in spam-adress.tab and
spammers.tab but they just change both and they spam again.

 

The email [email protected] is a legit user on my server. I am
using spamassassin, spf filter and RBL checks.

 

Anyone has any ideas how to block these ****ers.

 

Thanks
