After speaking to a few other Mac users, who use both Entourage and Mail, it sounds like Mail sets up multiple IMAP accounts differently than Entourage. In Entourage, every IMAP email has to have its own Folder, and then a Subfolder called INBOX, and then sub-sub folders for Sent/Trash/Draft. It also sets up its own Junk E-mail folder, for each and every email.
So what I’ve done, via Entourage custom Rules, is to get Entourage to move all IMAP emails into my top IMAP Inbox (see the attached pic of my Entourage Folders. The top one I’m calling MAIN IMAP).
My question is: how does Spam Sieve work with each IMAP account? Into which folder will it place spam. Further, now that I have Entourage moving all of the incoming mail so it moves and lands into the Main IMAP:INBOX folder, how can I get ALL caught spam to land into the Main IMAP: Junk E-Mail folder, so that I only have one folder to view.
I hope this makes sense.
