кто вызывает SpamAssassin? Какой MTA?
Может размер больше, чем установлено для проверки...
При чем тут "новые дыры"?

postfix Размер писем которые не проверяються около 70 кб... Я не про дыру в плане безопасности, а про способы обхода спамасасина

ну может косяки амависа?
а способов обхода спамассассина много... необученный он много пропускает спама типа нейтральный текст + гифка :)

у меня через spampd.
