Hello Mike, Yes, I am using a static IP address, but in theory, you could use a dynamic one. Nothing technically would prevent email exchanges between two boxes, as long as the SPF records are up to date and the DKIM is properly setup. Unfortunately, some ISPs are simply blacklisting full range of private IP addresses just because they are not officials / commercials. Kind regards, Andr?

I have dovecot postfix setup on my home server as well. I use a virtual server in the cloud as my mx record and mail relay and have my home record on dynamic dns. It's really effective.
