Are you using Microsoft Exchange?
I think you're running into "IMAP referrals" - a feature where the IMAP server can tell the client to
connect to a different server where the mailbox is really located. If you turn on JavaMail session
debugging and examine the protocol trace you might see the information about the referral.
Then you should be able to connect directly to the server it's referring you to.
