You neighter need access to port 5269 nor to 4000, 1863 or 5050.

Port 5269 is only used between Jabber servers, the other ports are not 
required because you just have to use the Jabber transports that 
communicate with the other IM networks with you.

For a Jabber client it's only necessary to open a connection to port 
5222 (or 5223 if you use Jabber over SSL). If you can't do this, there 
are different possibilities:
- (Best solution:) If your company has a SOCKS proxy, add SOCKS support 
to your client.
- If your company has a HTTP proxy it may be possible to use it. 
Different HTTP proxy hacks are possible. One of it is documented in 
JEP-0020.

use HTML for mail.
