As you can see, this article is really big, it took me a lot of time to write it, and I tried to be very precise, especially with detailed schemas.

The goal of this article is to explain how to make the most complete SMTP server configuration with OpenSMTPd :

  1. OpenSMTPd with MySQL and SSL
  2. Postfixadmin with httpd / MySQL / OpenSMTPd
  3. Amavid / Clamav / SpamAssasin with OpenSMTPd
  4. Secure your SMTPd with PacketFilter
  5. Install and configure the DKIM and DMARC tools
