I've got Interspire set up on a server with 12 static IPs and 8 SMTP gateways and I need to modify IEM to send through those IPs and gateways.
I'm evaluating PowerMTA on the same server but I'm not sure if I'll be using it. Any advice on selecting what MTA to use would be appreciated. The main reason I'm looking at PowerMTA is the throttling by domain feature.
Need to have DKIM, SPF, Domain Keys set up.
Configure Feedback Loops.
Also need to be able to throttle mailing speeds by domain and optimize IEM in any way possible.
Please post any questions.
