I switched from Entourage to Apple's Mail a few months ago and am mostly happy with the change, but there's still a few tweaks that I'm missing. I want to set up a rule or three that will change the subject headers of incoming mail messages. Specifically, I'm looking to add a listname tag to a few mailing lists that don't use them and similar tags for some other criteria. Entourage did this easily, but it's not one of the standard options for Mail and I haven't had any luck searching for a tweak. Found lots of other Mail tweaks... but not that one. It seems like it ought to be fairly simple, though? Anyone have any suggestions? Could it be done with an AppleScript? I could tweak a script to my own uses if I had a working sample to base it on, but don't know enough AppleScript to start from scratch. Thanks.
