I used to spend all my time maintaining e-mail quirks for my server. Adjust this, updated that, fix this breakage, yada yada. But then I decided to setup iRedMail which uses postfix, dovecot, certbot, roundcube, spamassasin, mariadb, ldap and all the bells and whistles. All I have to do now is make sure I don’t break it doing any software upgrades on freebsd. 10/10 scores after configuring and blacklist free. Source: almost 2 years ago
