Yes, certainly. But in my experience Exim has always put something in
the logfile if anything had happened. Something should be there.

I'll give it a try as soon as I a) have my personal exchange-admin
available again (i.e. tomorrow) and b) the issue shows up again (the
messages timed out and have been sent back).

It should be enabled. But I doubt that pipelining has happened,
according to the exchange-logfiles. We'll know more when I manage to
tcpdump a session.

Its tricky since the server definitly is quite busy. I could try to 
create a spare-server, though.
