Nice!  I never heard of Hmailserver until just now.  I was using the full blown
MDaemon for hosting my own email years ago.  Now, I just use it for some SMTP
relay for certain things at home - mostly alerts.

Yeah, probably SPF records and/or DKIM.  For some reason when you email me,
Google has a warning on the top that says "Be careful with this message".
Weather-station.org mail could not verify that is actually came from net229.org.
 

I have seen that before from other senders.  I had to do some magic with SFP and
DKIM records so that Mailjet could act as my external SMTP relay for my domain
without getting those type of warnings messages.

I still have my Exchange VM local all set up and ready to go, just never
switched over.  I was seriously considering it when Google was trying to exploit
business rate funds from personal home users to use GSuite.

Nice!  I don't have business service so my IP is technically DHCP even though it
never changes unless I swap my external firewall (ethernet MAC changes).  I use
a dynamic DNS updater just in case that uses an API to Cloudflare to update my
DNS records in that rare case it changes.
