EuroBSDCon 2025

Google and Microsoft dominate email, but it's still possible to run your own mail server provided you use modern protocols and maintain acceptable behaviors. This half-day tutorial will take you through configuring your own mail system, from a bare BSD operating system up through SPF, DKIM, and DMARC, and discuss the social rules needed to get your messages into Gmail and Outlook.

We'll discuss:

-Unix and email
-The Simple Mail Transfer Protocol
-Postfix and Dovecot setup
-Virtual domains
-MX and SPF records
-SMTP Protocol Tests
-DomainKeys Identified Email
-DMARC
-Webmail with Roundcube
-Rspamd
-Escaping and Surviving Block Lists

Attendees will leave with an understanding of how to configure a SMTP server and maintain it in an increasingly challenging environment.
