Domains listed in virtual_mailbox_domains are delivered locally. If a domain moves, the domain must be removed from your virtual_mailbox_domains. Postfix can't do this automatically. I suppose you could write a script to do an MX lookup on each domain and send you an alert if the MX points somewhere else. -- Noel Jones
