Comcast IMAP Can't delete extra folders?
So I just moved my Comcast Email over to the IMAP system, and It's working find on both my iMac and my MBP. However, on both computers in Mail I have three extra folders titled "Chats", "Contacts", and "Emailed Contacts". When I try and delete these folders, I get an error that Mail was unable to do so. These folders don't show up on the web interface for Comcast's email and I can't figure out what they are or how to get rid of them.
I tried contacting Comcast since their IMAP is still in beta, but the tech support person couldn't (or wouldn't) answer my question.
Just wondering if everyone is having this issue, or if it's just my account. Any help would be great!
