The two special fields define the virtual home directory and the mail location.

This database resembles the system password file in format, with two extra fields for Dovecot. OpenSMTPD and Dovecot can share an authentication database. Match auth from any for any action "outbound" Match from local for any action "outbound"

Choose a Vultr Compute Cloud instance with plenty of storage for the expected number of users. OpenSMTPD is the default mail server for OpenBSD.
This tutorial demonstrates a full-featured email server running on OpenBSD using OpenSMTPD, Dovecot, Rspamd, and RainLoop.
