Hello,
I have run my own mail server for about 20 years.
It is postfix, and has DNS, SPF and DKIM set up correctly.
DMARC?
The mail server is too small (much much less than 100 messages per day) so I
cannot check Gmail's tools for this.
Sending out DMARC aggregate reports will increase your footprint. (This is
possibly controversial, as recipients may tag aggregate reports as spam,
especially those who thoughtlessly configure rua to their gmail address...)
Ditto for abuse reports against failed attempts to authenticate on your server.
Best
Ale
