Hello. Let’s say I want to selfhost an email server (smtp + imap) that only will be used to receive email.
I only will send email internally (from my domain to my domain) and receive from 3rd parties.
Should I setup DKIM, DMARC, SPF and reverse IP lookup?
To be honest, I’m having a bit of hard time understanding the madness of email authentication. So I can’t figure it out by myself if those mechanisms are needed in my case.
I haven’t deployed anything, but probably will use Stalwart. It looks like it’s easy to deploy. Is there any other beginner-friendly email service I should read about?
Thanks!
