I have a number of things I want to get done in the short term:
- remove the mail server on my gateway box at home and start using a mail server on an internal box
- Configure my external mail servers (out there on the Internet) to use TLS when talking to each other
- Configure those same servers to accept mail from that new internal mail server
- Stop using Postfix on servers which only output mail. Start using something like msmtp or nullmailer… or something easier? Perhaps opensmtpd, see smarthost in docs
Items 1-3 are done.
And #4 is done, on on server. I may spread that to more servers soon.
