Your connection may be fine, but theirs isn't.  Do some basic network 
tests - try pinging and tracerouting to their server.

Try forcing the mail manually, and keep killing the process if it looks as
if it is going nowhere rather than leave it to time out on its own.  

Often there isn't much that you can do in such situations unless you can
get hold of someone at the other end to analyse the network problem
between the servers involved in more detail.  I sometimes find that I can
spool such mail on another server that has different routing and enable
delivery that way.  I have exactly this problem with the very service
provider mentioned in my earlier posting about Zimbabwe being disconnected
- TelOne - to whom delivery is sometimes impossible.
