    Greetings, I host a large amount of domains on my dedicated cPanel servers and several clients have requested that I use outbound mail filtering system using a third party filtering service, much like an inbound filtering service for spam. This has been requested due to the shared environment easily being blacklisted causing bounces from clients when sending email from the shared server's IP address which can easily be listed.

    Is there a way to specify an external outbound SMTP IP address on a per domain/account basis?

    Such as sends email through and external outbound SMTP IP address of and would send through an external SMTP IP address of, etc...
