    AntiSpam Profile include a feature ' Image spam scan' that you can enable to attack such spam.

    This " image spam" feature has a very high false positive rate in my opinion! If you receive legitimate image based mail and cannot easily whitelist a couple of senders, then I wouldn' t use it... It will drop nearly every image based mail!!!! cheers.roman

    I tried with&without and always had false positives... Actually it is no problem, because in all the installations we have, there is hardly any spam! The image spam feature was the main reason for false positives, so we decided to not use it anymore... cheers.roman
