Hello, Thank you for your quick response. I apologize if I was not completely clear. I have set up virtual domains and domain aliasing before, all going through the same interface sharing the same IP.
In this case, I need domainA.com (thus mail.domainA.com) and domainB.com (thus mail.domainB.com) to go out using different IP addresses. So network Card 1 will have IP address of 200.nn.nnn.30 and Network Card 2 will have IP address of 206.nnn.nnn.65 In the case that domainA.com gets blacklisted by IP, domainB.com will not be affected. Despite the fact that both domains are on the same physical machine, they must not share any mail information or records (SPF, MX, A, CNAME etc) Regards 2009/10/27 Frappy John <frappyj...@gmail.com> > I hope you realize that the sender (with the cooperation of his ISP) > determines which mail server his outgoing mail goes through.
