Hi, is it possible to set up duplicatesuppression based on the mail content? Using a md5 sum or similar? I ask because we have a problem with a groupwise (6.5?) Server that does not generate unique Message-Ids if you setup a mail forward (you even cannot really forward a mail, groupwise generates a new mail with the original mail included and with sender postmaster). Are there other known problems with duplicatesuppression switched on?
