I regularly get a few connection timeouts from the spamd service, it's
free and best effort so it's hardly a problem.
Today there was a period, 18:00 - 18:20, where exim couldn't connect at
all, no route to host/conn refused errors.
Since then I am seeing far more connection timeouts.
May indicate a problem on the box running that service, not sure.

Nigel
