I've tried imapsync, that seems to work well, but, what options do I have for doing accounts or domains where I don't know user's password ?

It depends on whether you're copying from an existing dovecot you control, but you can use the master password extension user={user}*{masterid}, password={masterppassword} in place of {user}/{userpasswqord} for imapsync to get the job done.
