filter attachments for the presence of macro's
A lot of virusses spread via macro's in Word-files (or Excel). Most clients however work with word-files as attachments on daily bases. They rarely send/recieve legit mails with macro's inside however. It would be nice to be able to block all word (or excel) files containing macro's.
I don't know if that should be an attachment-filter option or an antivirus option.
