The problem was along these lines.  Port 25 seems to be blocked for 
outgoing on the network I was testing the e-mail client.  I added 
listening on port 587 for situations like that and everything is working 
now; or rather it was always working and I just now realised it.  Thanks 
for pointing out the most obvious reason.  It could have taken weeks for 
my brain to turn on.

Yes, you're right.  I reset to 30s and from some hosts it takes about 
35s and from others about 3s.  I must have made a mistake when I 
measured 60s.  I have set the timeout to 5s, which I think is the 
default for exim 4.6 (I have 4.5).

Thanks again.
