He never called me back on Friday - I'm not going to attempt to troubleshoot
something without having *some* idea of whats going on at the far end.
I did some research on IDS - I asked our firewall guys :-) As far as I can see
IDS can have nothing to do with this; he must have some kind of firewall as
well (maybe a PIX, although he told me otherwise).

I have looked fairly closely at some of my logs and it looks like there may
well be some kind of configuration which will not talk to a postfix server - I
can see a fair number of IPs which do nothing more than connect, then
disconnect.

If and when this guy gets back to me, I'll snoop the traffic and see if that
tells me anything more interesting......
