The kernel ships by default with about 8k file descriptors available.  If
the system just does email, then you probably have a ulimit setting of 1024
by default, and you can change that by (as root) doing a ulimit -n 2048, or
4096, or whatever and spawning the shell that starts exim, or the shell that
starts postfix - whichever is exhausting its resources.

There used to be some header twiddling you had to do in 2.2 to get select()
to work properly, but I don't think thats an issue anymore.

The 5 year plan:
In five years we'll make up another plan.
Or just re-use this one.
