Welcome to the mailbox.org user forum!
XMPP and RFC 7711 (POSH)?
Proposed
Can I somehow use RFC 7711 with the mailbox.org XMPP/Jabber service? If so, what should I put to the /.well-known/posh/xmpp-server.json and /.well-known/posh/xmpp-client.json files?
Using this method could prevent certificate validation errors for both c2s and s2s connections.
I like this idea 
No connection
Real-time notifications may not work
