Postmaster (computing)

In electronic mail, a postmaster is the administrator of a mail server. Nearly every domain should have an e-mail address like [email protected] where errors in e-mail processing are directed. Error e-mails automatically generated by mail servers' MTAs usually appear to have been sent from the postmaster address.
