Maybe, though some > postmasters care not, some actually do check. I was just wanting some clarification - I know the answer has to be yes (look at how many shared hosting solutions are out there) - so why is it not possible to just get a yes or no answer? Can I set up DNS (and MX records) for several different domains to point to the same postfix instance/host/IP address and reference that same postfix instance/host/IP by different DNS host names (smtp.example1.com, smtp.example2.com, etc), and have everything just work? I'm guessing, 'Of COURSE, dummy!' is the right answer? I guess the question is just too simplistic and basic, so my apologies... -- Best regards, Charles
