Serious network problems are kinda of a big problem...
We deliver messages all over the world. This is a common occurrence.
Exim needs to panic on real problems not just because a connection dropped!
Those messages belong into the main log.

What does "quit" mean? Exim will accept a limited number of connections
(I believe 20 is the default) at a time, and then turn away additional
connections.
How can I increase the limit? I want at least 100 simultaneous connections.
The problem was that Exim after delivering some messages did not again pick up
listening to the SMTP port. The "exim -bd" process was simply gone for good.
