I have a raspberry pi running postfix. I Realised unless I open port 25 I absolutely cannot receive emails (I have 587 open and can send but not receive them). However I heard there are scaries online which someone could potentially send emails from your server without consent. I believe as well my ISP doesn’t block port 25. Is there anything I should do right now before opening port 25, or should everything be safe enough?

    100% agreed. It’s well worth outsourcing to someone else for $10/mo versus the amount of work it takes to do it well unless you’re a large business.

    I’d make this argument for DNS too - a lot of work for how easy it is to pay someone else to handle it.
