I am in the process of getting Return Path Certified. One of their criteria for certification is the IP can only be used for sending templated email ( newsletters, notifications, ect.. ) and not personal corporate email. This is because corporate emails can be compromised, and therefore risks more exposure.
My question is how do I go about setting up domain to send via 2 separate IP addresses
When connected to the server from a script, how do I specify which IP is to be used when sending out the templated emails?
I would think I could just setup another hostname ( mail2.mydomain.com) for the second IP, would I also have to setup a seperate domain (mail2.mydomain.com) on the server, and just limit access to only local IPs?
