Setting up a mail server with the outside world?

Question

Mail server

Good afternoon.
Bought a domain. We want to install a local Iredmail mail server with our purchased domain. How to connect all this business? I understand that you need to make a PTR record with the provider. And where to enter MX records? So that when sending letters to our addresses with our domain name, they come to our local server ?.

Answer 1

You need to make the appropriate entries in dns.
First, for the domain at your registrar, the name servers serving the domain are indicated. After that, at least mx records are registered on these servers.
But given the question, I recommend that you contact a specialist or connect one of the cloud-based email services, email servers require a fairly high qualification from the administrator.

Answer 2

in this case, you need:
1. iron
2. AXIS. some freebsd or linux
3. set up dns 4. set up
iredmail (you need knowledge of postfix, mysql , php ) try step by step to understand, read what administration is and how it starts
