Hi!
in the last week or two, we have been getting some spam that spamassassin doesn't seem to recognize. A common feature of all these messages seems to be that they contain lots of special characters (~, ^, `, and others) mixed into the text. I put some examples up at http://marie.vtl.ee/spam.txt
Would a rule to calculate some kind of "special chars" vs "total chars" ratio be useful? Does anybody have that kind of rule already?
Start using SURBL, as far as i can see in your samples all would have been tagged.
Bye, Raymond.
