Question above.
How to send mail to NodeJS from your domain without using third-party services such as Yandex or Google Mail for Domains?

Answer 1

for that you need some smtp server on your server. Not necessarily full, the main thing is to be able to send messages.
For example postfix.
In general, this has little to do with nodejs, and a separate large area, how to set up, configure, make sure that letters from this server go where they need to, so that they do not fall into spam, dns settings, and so on.
how it all works, in nodejs take nodemailer and specify the address of your mail server in the transport settings.
