Originally I was on a business connection, so no port blocking. I moved to a residential connection at home and they blocked port 25. So I enabled my VPS in the cloud to relay my mail to the imap server in my home. It's a very simple setup. I only allow a couple IPs to relay anything through ( my home IP and other VPS's). Any other connection must be delivering to my IP or it's rejected. Then In the transport maps tell it to utilize a non standard port
domain.com relay:[home.domain.com:28]
On the home server's postfix I just define the relay host which also uses a non standard port
relayhost: [vps1.domain.com:26]
At this point you just have to setup your postfix/dovecot config how you want. I'm using postfixadmin and both postfix and dovecot use mysql to determine domains, users, and passwords.

Which part? Hosting the email server at home or the relay in the cloud?

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.

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
IP addresses just because they are not officials / commercials.
Kind regards, André

Non static ip'd mail servers are also blocked because they're typically spammers.

Stephan h, may I ask why you do that? Just out of curiosity.
Thanks,
