XMPP Federation Setup

NOTE: Only support "Type 6" federation. Please refer to XEP-0238: XMPP Protocol Flows for Inter-Domain Federation

1. generate client certification and key for each XMPP server based on local CA.

   • Case 1: The common name is the peer domain name.
   • Case 2: The common names includes the peer domain name.
   • Case 3: The common names match the peer domain name with wildcard.

2. Create a directory for each XMPP server in /etc/erisemail/cert/client.

   • The directory's name is the domain name of each XMPP server.
   • eg.: /etc/erisemail/cert/client/erisexmpp.com

3. Copy the corresponding ca certification file, client certification file, key file and password file into the related directory
