How to set up mail on the home server?

Question

Email

I want to set up mail on a home server sites a few.
Problem:
1. the Internet will naturally disappear and mail will not be delivered!
2. it's impossible through my ip - the filter and the khan will get into the spam .... I
thought I could make Postfix + Davecot and through www.serversmtp.com/ru - so that the mail is stored there and sent through it?
What can you advise?

Answer 1

Use any mail service - from Google, Yandex, there are many of them.
Usually providers can block ports 25/465/587 for sending mail to clients to block spam mailings, usually clients are given a relay mail server for sending, sometimes even for receiving. In general, there are many services where mail can be stored for a small amount of money.
From another option - buy a cheap VPS on Amazon / Azure and set up a mail server there, since the instructions for setting up postfix | exim + mysql + Web face for mail and managing hundreds of thousands.
