I am moving my email behind a dynamic IP, and I will need to SMTP relay outbound email in order to avoid spam lists.
My domain is hosted through a BlueHost VPS running EXIM. I am wondering what I would have to configure to run two domains outbound through my one VPS using SMTP Relay and have me email not be market for spam.
If I do relay through my VPS, will I be able to do so with multiple domains? For instance, thedilldesign.com and virginiaseo.org are both my domains/companies. thedilldesign.com is hosted on my VPS, though the domain is registered through GoDaddy and DNS is held by CloudFlare. Would I be able to send email using thedilldesign.com domain name from my dynamic IP address and relay through my static IP on my VPS? Would these outbound emails have an appropriate reverse SMTP banner and RDNS so that I am not flagged as spam? Would I have to configure thedilldesign.com to be on its own static IP with its own mailserver, or can it share the relay capabilities with the other domain off of the same IP?
Any information on multiple domains through a VPS SMTP Relay is welcome!
