How to set up your mail for a domain?

Question

SMTP

So.
1. I thought to raise a mail server on the server. Dissuaded .
2. A friend advised GSuite.
2.1. I realized that this is hell.
Problems:
I can't figure out how to set up a no-replay host (yes, it didn't work with this answer and man-ohm).
I tried to send emails from the site - it does not work. Somewhere it is necessary to mark the checkbox that they say I allow any authorization, God knows where.
A whole ton of settings - nothing is clear, everything is very blurry. How to deal with this GSuite? There is no complete article about the minimum setting.

Answer 1

If you haven’t mastered GSuite, then there are analogues: fastmail.com (which I use), pdd.yandex.ru (currently free).
You need your own mail server only if:
a) you have some very exotic requirements;
b) you will have many users, but little money;
c) you are paranoid
