Even if you have a proper clean IP, running a mail server is a hassle imo. By far having a single relay to send is fine if you get things set right, but also dealing with incoming spam is just way more work than paying to have it hosted.

I much prefer paying for email hosting and just dealing with outgoing emails if needed.

  • Probably unrelated, domain spoofing is common, but miss-configured mail servers will accept those emails and process auto replies. They can also abuse input forms to try and send out emails, but that typically does not have much control over content.

    If you are getting more emails than you can deal with, than can be used to try and mask other emails by burying them in a large email volume. In that case you should be looking for emails from important accounts you do own (eg banking.)

    If you have a high pressure hot water system, then the heater doesn't touch what comes out of the tap. In those you have a closed system from the heating to a tank. That tank contains fresh water, but the heating loop only interacts with it via a heat exchanger.
