I setup a mac, and all was working fine, until the user discovered smart mailboxes.

So my user has a smart mailbox which shows her all unread mail, all mail in her inbox, and any mail that is flagged important

When new email arrives it is showing up in the smart mailbox, then about 2-5 minutes later a second email shows up a duplicate of the first.

I have no clue why.

Her email is setup with the isync connector, and imail is setup to sync with exchange.

If I log into the email on the web, I only see one copy of the email, so it is definitely only the imail program showing two email messages.

So how do I correct?

1) troubleshoot this and fix
2) remove zimbra connector and delete the email profile and recreate it

What is the proper way to have email setup for macs?
