My company has signed up with Google Apps for Business so I have a gmail address of the form email@example.com.
I use mcabber as a chat client and am unable to connect using my working mcabberrc file (which works with my @gmail.com account) with the jid set to the company email address.
I have tried several different configuration settings related to ssl and setting the server/port, but the more research I do, the more it seems it should not be necessary (just setting the jid is expected to work).
With the default mcabberrc, mcabber reports:
