Postfix - jonatello/lab-musing GitHub Wiki
This guide is for configuring Postfix, a Message Transport Agent (MTA), to send mail using the Simple Mail Transfer Protocol (SMTP).
A good guide to reference is https://www.freebsddiary.org/postfix.php
DNS
The first thing necessary is to configure DNS properly. Ideally, we have three DNS records to configure:
- An A record pointing to the public IP
- MX record(s) telling other mail servers where to deliver messages
- Reverse record (PTR) pointing the IP to the domain name
Configure
Install Postfix via pkg
pkg install postfix
