X-Mailer: GoldMine equated as spam...

[Ken Morley]

I have a mailfilter running RedHat ES3, Postfix 2.2.8 (chroooted), amavis-d, SpamAssassin, etc. and it is generally working very well. I have had a complaint about a message sent using GoldMine being rejected. The NDR included "Remote host said: 550 Error: Header X-Mailer indicates message sent by spambot". The X-Mailer tag was "X-Mailer: GoldMine [6.50.31113]" and, in this case, it's definitely not spam.  I have searched and cannot find the rule responsible for this.  Does anyone know where this rule exists and/or how to disable it?   This rule seems a little too general as many legitimate messages are originated from GoldMine's MUA. Thanks! Ken Morley
