Basically you tell it, not trying to sound funny there, but I guess different MTAs are told in different ways..
As an example I use postfix as our inbound gateway, if I wanted to set it up as a secondary MX for domain.com I'd basically tell it where to route mail to domain.com to, and that would pretty much be that barring some tweaking. Just a personal opinion but I'd be tempted to use a third party for a secondary MX - the one I use is dirt cheap and deadly reliable so I'd sooner not worry about another box to look after.. regards, Paul -- Paul Hutchings Network Administrator, MIRA Ltd.
