Truthfully, I've previously always been in the situation where another 
sysadmin handled the mail server, or using 3rd party mail software.

Main mail server is not a RaQ - it runs a 3rd party mail server.  But 
that shouldn't be a big concern.

Yes.  Some of them, at least.

Which is what's got me slightly worried... that the RaQ will get 
confused and try to accept/reject mail for those domains (during 
failover).  Which will mostly get rejected, because those accounts 
don't exist on the RaQ, only on the main email server.

We got away from using the RaQ for email because we have a lot of 
domains who all want 'info' and 'orders' and so on, and the other 
server handles that a lot better.
