KB / Account Control Panel / Goodies :: Jabber IM / Do you support secure (SSL) Jabber connections?
From DreamHost
We do!
In order for secure Jabber to work, you must have a secure certificate already set up for the domain you're using jabber on.
That's it! If secure service is already running on that domain, then when you set up jabber users on that domain you'll be able to use jabber securely!
Make sure you set the port to 5223 on your jabber account!
Not all Jabber clients actually support SSL connections, so if you're interested in this, make sure you check out if your client does.
Tips for clients (aside from changing the port):
PSI - Encrypt Connection: Needs to be set to Legacy SSL
Adium - check 'Force Old-Style SSL'
