Receive mail for multiple Internet domains

Where do I find the procedures to setup Domino Mail servers to recieve internet emails, please pinpoint. The Domino help does not have it. Previously my Domino Servers receives email for eg. @mydomain.com for Notes domain ETAG . But now I just registered some new domain names and I would like them be sent to domain ETAG eg. @myfirstdomain.com, @myseconddomain.com , @mydomain.com all belongs to the same ETAG domain. And also where do I find documents on how to setup up routing emails for other domains beside my ETAG. Just like an email hosting service??? Thanks

Sorry to have to tell you this but the info is all available in the Domino Admin Help database.

To give you a “pinpointed” hint, you should start by looking up “Global Domain document”.

P.S.: The Help DB are often not the most user friendly source of info but they do cover all the basic stuff.
