I want to set up multiple mail servers within one dedicated virtual server in Mediatemple.
For example, my server's primary ip address is 203.156.0.xx. My server has another IP address 203.156.0.yy. The server's outgoing mail server is 203.156.0.xx.
Currently, all domains regardless of which IP address they use have 203.156.0.xx as their mail server. Is it possible that the domains under 203.156.0.xx use 203.156.0.xx for their mail server and domains under 203.156.0.yy use 203.156.0.yy for their mail server?
Any advice will be appreciated.
