The folders that re-creating themselves:
I have filters set so these messages should be going into the appropriate folders. Everything was working just fine on my old iBook G4. Mail on my iBook G4 (running OS X Tiger 10.4.11) still works just fine. When I got my new MacPro, strange problems started with Apple Mail …
I’m using Snow Leopard 10.6.2.
The duplicate messages are going into dozens, most likely hundreds, of other folders. I disabled all three of my Clearwire e-mail accounts, but the duplicate messages still keep on coming …
My DreamHost accounts are set up in Apple Mail, using POP.
I’m really not sure what you are talking about when you mention the advanced mail account features …
I still have mail that arrives in the Inbox. All of my important e-mail is filtered to the appropriate folders. The filters are working just fine.
Problem is these self-creating folders, and some mail (not much though) is coming into these mystery folders, even though I have the filters set correctly.
