Re: a dns mail server question.
Real Simple. Use IPFilter or some other utility that does NAT/Port
Redirection. On your current mail server, redirect smtp port 25 and/or
pop3 to your temp. mail server. Leave your DNS settings like they are.
They should still point to the public IP on your mail server. Clients
connecting in from the outside should never know the difference.
