<p>For a long time now it's becoming a real nuisance to self host
email servers. You need a static IP with clean / good reputation +
nspf, dkim, dmarc and all that while most your mail will be routed
trough google anyway. It's probably only worth it for big setups
or educational purposes.<br>
<br>
As you only send to yourself, why go through a third party at all?
Maybe go for a KISS setup answering: How do I get a message from
the server to wherever I need it. Does it have to be email at all?
The options are vast depending on your specific needs. <br>

<p>You can always use a different gmail account to send from the
server.</p>
