The timeouts are a symptom of the problem, not the cause of the
problem. Raising the timeout value in Exim won't accomplish anything
since the timeouts are being caused by something other than Exim.
What Marc was suggesting is to check your MTU settings with your ISP
on your DSL line. If you are running PPPoE on your DSL line, there
could be an MTU problem that is causing inbound connections to hang,
which would give you timeouts in Exim.
This a very common problem with people running mail servers on DSL
circuits that run over PPPoE.
If you aren't familiar with MTU settings, call your ISP and they may
be able to assist you.
