Thanks, JohnB
Two thoughts,
1. Which file contains this information so we can review settings when mail isn't where we expect it?
2. If you register your domains with easydns (a typical DNS provider), you can configure multiple hosts within your "domain" , even if you don't use dynamic name service, and assign mail to the desired host. Plus they act as a backup mail server and when some idiot severs your phone cables, you can reconfigure & be back on line in a couple of minutes !

JohnB's method
db domains setprop test.com MailServer 192.168.3.20
where test.com is the virtual domain in question and MailServer is the IP address of the SMTP host.
signal-event email-update
This will send all mail for test.com to SMTP host at 192.168.3.20 but will deliver all the rest locally.
