I have 4 different email accounts in Mail; therefore, there are 4 different inboxes.
When I select the unified Inbox, I should see all emails listed from all accounts. But I don't.
What could be preventing seeing all email in unified inbox? 3 email accounts are POP; 1 is MobileMe IMAP. When I control-click on unified Inbox, all email accounts are in the drop-down list. One of the POP accounts shows nothing in large box below that.
(Snow Leopard 10.6.8 with Mail version equivalent for Snow Leopard.)
