>I am having a hard time understanding. Does this allow you to send / receive anywhere? Across the internet I mean. what external server does it use for 'stapling' the connection or is it also expected that you self host a relay server + set up the necessary ports etc. Do both ends require a relay server? Sorry, I have spoke too soon. I see now it uses a public relay by default, and you can self host as needed. Sorry for the unnecessary comment!
