So I've already enabled the option for sending mail with a sites dedicated IP address in the exim configuration. But what else do I need to do?

As far as Reverse DNS, I can configure that at our data center. But would the hostname still be the main hostname of the server just on another IP address for that clients dedicated IP or should I just setup a separate hostname for that account?

Do I have to manually configure any other files or options?


We're run-in 92.0.3

Hey there! I just make sure that the rDNS on the main shared IP points back to the hostname of the server. No matter what IP address does the sending, the hostname will still show up in the mail headers, so you want to make sure it has properly rDNS.

Yes so the main IP of the server has proper rDNS, So no matter what even as a reseller it will always point back to the main hostname of the server would that be correct? That is just by design of exim?

Do the SPF records need to be modified in some way, as the Email deliverability report Says Manage Your Domain and shows the main host name, and just the main IP. Do these records need to be setup somehow for the additional IPs or is it fine?

Says everything is configured correct

Thanks!

Unless you are using custom mailhelo entries as outlined here:


you'll only need to worry about the rDNS for the main hostname and not any other domains on the system.
