I look for information about this problem at forum, but i cant find any about this way spammers have to round the spam detection.
Thats an example of they do it:
De: Viagra.com <email@example.com>
Asunto: Online Doc Tammie
faq-mac.com is a valid domain for me, but i cant find a way to round this problem. I receive … mmmmm … over 50 of this kind (from different email directions from my domain) by day.
I’ll try to avoid this behaviour … but no luck. If the email adress go to the white list, catch all the spam as legitimate: if i train it as spam, i lost all these valid mails.
I receive over 500 smaps by day … sometimes even more.
thanks in advance!!
