Domain Checklist for custom mail server built on DigitalOcean
Raw
README.md

How to build your custom mail server?

These instructions are specific to opportunities to automate tasks related to a custom mail server deployed using the following instructions: https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-server-using-postfix-dovecot-mysql-and-spamassassin

Database setup

  • Add the domain name to the virtual_domains table
  • Add any user email addresses to the virtual_users table

DNS Setup

The following configurations are DNS related.

DKIM Setup

Ensure that the DKIM test passes - I suspect this needs to be completed just for the mailserver configured in your domain MX records: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy

SPF Setup

This is an API entry on DNS. You MUST have an SPF record for every "mirror" domain on your mailserver.

DMARC Setup

See https://dmarc.org/overview/
