Answer 2

Literally two days ago I set up postfix on centos 7) however, it's not clear what apache has to do with it)
I used postfix + dovecot + openDKIM. Step by step:
1. Good article for the first two applications, despite the fact that it is for centos 6, everything is true for centos 7:

2. Adding support for tls encryption:

3. Set up openDKIM:

4. Set up SPF and DMARC (just TXT records for the domain, google it)
5. Set up PTR (what would IP refer to your domain)
6. Close access to ports in iptables
Because I have a mail server on a separate machine so as not to expose the main server to DDOS attacks, an additional thing that I do for my mail server is hide the sender's ip address:

I'll add that I had a server transfer. The configured old server according to these articles has successfully worked for a couple of years

You are not looking there. They write books on setting up mail servers.
