I know this may be a newbye question but I really need an help.
I am trying to fight the last type of spam, the one in which the spammers use typos to fool spamassassin.
So I am trying, without success, to write a rule for the System Filter to block every combination, for example, of the word "viagra". Something that can match also typos like "VIAjGRA", "vIAgGRa".
What I mean is... how can I write a rule that is able to recognize the word "v*i*a*g*r*a" where the X are every possible character?
Do you think it would be more correct to put it in the ACL check section?
Thank you very much!
Lukas
