Editing Introduction to a Self Managed Life: a 13 hour & 28 minute presentation by FUTO software (section)

===== WTF? OpenVPN was set up so we DON’T open ports; why are we talking about opening ports? =====

If you are accessing your mailserver using OpenVPN (AS YOU SHOULD), this doesn’t matter. You will be opening port 25 to the world so you can receive email, but for the rest of the ports, these are ONLY NECESSARY IF YOU WANT CLIENTS WHO ARE NOT CONNECTING TO YOUR VPN TO BE ABLE TO LOG INTO AN EMAIL ACCOUNT AND READ THEIR MAIL AND SEND MAIL ON YOUR MAILSERVER!!!

Plus, the self-hosted phone system is going to require we allow some external IPs belonging to our SIP trunking provider (the thing that lets you receive &amp; send calls to other phones outside your house) to access our server anyway, so you might as well learn about aliases now.
