Installing Postfix and Dovecot and setting them up as explained at https://help.ubuntu.com/lts/serverguide/postfix.html
Then setting all apparmor profiles including Postfix and Dovecot to enforce mode.
Postfix fails to send a TLS protected email because Dovecot can't connect to /var/spool/postfix/auth/private because when Dovecot's apparmor profile is set to enforce mode, apparmor denies Dovecot access to /var/spool/postfix/auth/private.
