# 2. Have a Let's Encrypt SSL certificate for $maildomain. You might need one

# them anyway.
# 3. If you've been toying around with your server settings trying to get
# postfix/dovecot/etc. working before running this, I recommend you `apt purge`
# everything first because this script is build on top of only the defaults.
# Clear out /etc/postfix and /etc/dovecot yourself if needbe.
