I am recieving lot of stock related spam mails which spam assassin is not able catch as spam. I have added Sare_stcok.cf file. I cant use imageinfo, fuzzy ocr as iam using 2.6o ver of spam assassin i think. I have enclosed the undecoded letter mail of one kind below. Can you plz help me to make this kind of mails as spam.
Image spams are hard to catch using normal header and body rules, especially when they don't have any urls in the body. Enabling network tests and installing the patch for the URIBL will probably help some.
