I have two IMAP email accounts setup in Versamail. I can manually get messages and manually sync the server folders, so I know the password for both accounts is entered in correctly. When I have it set to auto sync server folders, I always get a popup that the auto sync failed. Any ideas?

I've been using Chatteremail on the free trial and it works perfectly, but I'd rather use VersaMail if I can get it to work since it came with the phone.

This is on a 700p with Sprint.
