6. Email Routing
At any point in time, email should be routed to one mailbox for any particular address. The migration process for a mailbox should start with the update of any routing for the email address and the setting up of appropriate forwarding from the local mail server to Nexus.
Direct deliver departments wishing to migrate should carefully consider the point in the process when they would like to move from direct deliver to oxmail routed (personal routing). Delivering email to the department and then that email being routed back to Nexus is not sustainable and may cause mail loops if the two systems are not kept synchronized. A synchronization process is in place with the oxmails and occurs automatically minimising the likelihood of mail loops and other routing anomalies.
