13. Other Considerations
Automated Systems: Within your unit, automatic monitoring or other system processes may be using a local SMTP server to send email. Post-migration, a local SMTP server would either need to be maintained, or all automated systems reconfigured appropriately.
Hybrid Systems: Some units may wish to run hybrid systems, where some users continue to have mailboxes located on local systems and some on Nexus. This case is not unusual. Careful attention should be paid to mail routings in this setup and you are strongly advised to utilise the Oxmail service for routing users' email in these circumstances.
