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, André

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.

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.

thatis not secure and you might as well use gmail
It is not so hard to just get a static IP and put a mail server up.
fit/pc has perfect boxes for this, run on about 15w/h power

Why do you think this isn't secure?
Gmail wouldn't let me run my own spam and AV solution. My external server gives me full control, with sendmail, MIMEDefang, SpamAssassin, ClamAV, dovecot, and procmail. I could, in principle, keep a remote copy of all my mail there and dsync it to my home server. I'm using fetchmail (with SSL option) only because I didn't understand dsync when I set it up.
I'm still a bit unclear on how dsync decides which users to sync. All my users are real system users, not virtual users. I'd like to retire my 3 older accounts on my home system to never receive email again, only provide it for archival reading, and direct all my mail to new accounts that could be dsync'd to the leased external server. So I'd want to limit dsync to only sync the new accounts. Which might even be virtual.
what I said, not what you said...
