Mail.app and purging of moved messages with IMAP accounts?
I use multiple computers and I don't remember to quit out of Mail.app going from one of my Macs to another and don't want to but I'm getting tired of having to file the messages twice (or more). Is there a way to set Mail.app to do the automatic instant purging (or expunging) of the messages from the originating folders without having to quit out of the application? This seems to be the default behavior for nearly every other mail client I've used, including Entourage and is an option in Outlook and Outlook Express (PC).
