I am configuring a dovecot-auth only installation. Postfix will use dovecot for sasl auth.

Here is the configuration I’ve settled upon. I welcome suggestions for improving this setup.

Thanks.

# doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.3-RELEASE-p5 amd64
auth_mechanisms = plain login mail_max_userip_connections = 80 mail_privileged_group = mail passdb { args = scheme=SHA512-CRYPT /var/db/dovecot.users driver = passwd-file } protocols = none service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } userdb { args = /var/db/dovecot.users driver = passwd-file } verbose_proctitle = yes
