Question Different outgoing IPs in Qmail

[bekway]

I have three IPs and would like to allocate each one to different domains in smtp for sending mail (as they are set in hosting settings and DNS). Right now all hosted domains send out e-mail using only the primary IP regardless of the IP used in hosting settings. I'm in Plesk 12.5 and CentOS6.7 using qmail.

You can do this through the Plesk Panel, in the Server-Wide Mail Settings, but only with Postfix. Switching to Postfix is quite simple.

I haven't done it myself, but this guide appears to deal with chanigng the IP address on a per-domain basis with Qmail.

I tried the smtproutes qmail control setting but emails still go out through the "primary" IP. Are there any other solutions. Changing from qmail over to Postfix seems to block messages sent from some websites, especially orders from e-commerce sites, so this is not the best solution.
