Thanks for that. I've just tried altermime but it appears that it only operates on the message header and not the MIME headers in the body. I played around modifying altermime to scan the body too but I think I'm getting into the "thar be dragons" territory with that approach. I think I can do what I need to accomplish more accurately & efficiently with sed and procmail. I'm just not quite sure how I would go about configuring postfix to make this operate on outgoing mail. Any advice ?
