Despite the entire web saying don’t, I’ve done it. What should I do next to ensure maximum safety?

I’m using mailcow. The UI is only accessible when connected to VPN and is hosted under a different domain than the mailserver.

I have outbound messages proxy through smtp2go, but I also have all my DMARC config added to my DNS provider (SPF handled via smtp2go).

Anything else to be aware of?
