+- A user's mail is in `~/Mail`. Want a new email address? Create a new user and just add them to the mail group, be sure to give them a password with `passwd <name>` as well. Now they can send and receive mail. Look up using aliases too if you want for more cool stuff. Dovecot should autocreate the directories as needed.
 - All dovecot configuration is just in `/etc/dovecot/dovecot.conf` instead of a dozen little config files. You can read those in `/etc/dovecot/conf.d/` for more info, but they are not called by default after running this script and the needed settings are edited into the main config.
 - Your IMAP/SMTP server will be `mail.yourdomain.tld` and your ports will be the typical ones: 993 for IMAP and 587 for SMTP.
 - Using non-encrypted ports is not allowed for safety! The login is with plaintext because that's simpler and more robust given SSL's security.
