Hey folks,

We are planning a migration away from Dovecot (sorry) to Google Apps and are trying to figure out how to migrate the contents of user mailboxes to the new provider. Normally we would use an IMAP migration tool to log into each user's mailbox on the old and new providers and transfer the data that way.

However, there is no central directory service; all accounts are local. We have a large number of users and for both management and security reasons it's not feasible to compile a list of all IMAP passwords.

Is there a way to log into user IMAP accounts on Dovecot using a central administrative credential?

Thanks!
