Hi, since a lot of spam nowadays tries to get past the filters by multiplying random letters, wouldn't it make sense to introduce normalization plugins to spamassassin?
These would run over the mail once before the actual scanning starts, and perform transformations on the decoded mail body. Some functions I could think of off of the top of my head would be: - reducing multiple consecutive letter instances to one occurance of the given letter - Transforming html-entities to their given roman letter equivalent - removing all non-alphanumericals from the mail body This would require a new new rule calls (e.g. normalbody), to avoid breaking existing rulesets. Would this make sense? Can this be included into spamassassin, or are the current internals structured in way that makes the introduction of such plugins hard/impossible? Regs, Sven
