[tor-talk] Peering

[blobby at openmailbox.org]

"Yes. We have direct peering (email doesn't leave Tor at all) with 
Torbox, Lelantos, bitmessage.ch, mail2tor, ruggedinbox.com, and any 
other mail server that is reachable on a .onion address."

My impression is that .onion servers thus operate as their own DNS hence 
this claim from http://sigaintevyh2rzvw.onion.link/faq.html is accurate.

Could someone briefly please explain how "direct peering" works.
