Yes - the primary MX was "High" priority - the backup MX was "Low" - the backup server had only been told it could relay for the domain (not to accept / process mail for it).

Will try what you suggest but thought there should *really* be some way to do it from the UI - it has options for backup DNS so backup MX is the next logical step?

I am always slightly wary about making "manual" changes to the config files on the RAQ's as there is a good change an update will come out and may wipe over the changes you made - things stop working and you are left to figure it out! :)

Thanks... David.
