Im hosting several domains with plusnet, and one single 'catchall' mailbox.At the moment, exchange is set to pick up all defult emails sent to mailbox@bridgesltd.co.ukOur email systems all work on smtp, and we dont have an option to setup individual mailboxes on the isp end to deffrenciate between domains.I can easily add the email address into the users profile for the new domain and have it forward to the other domain, but we need to be able to send emails out on another domain (not the bridgesltd).Does anyone know of a way this can be done? I look forward to hearing any responses. Adam (exchange 2003)
