The limit here should purely be the internal table that holds the list
of incoming processes. The daemon process should not have any file
descriptors open to the incoming SMTP session after it has been accepted
and handed over to a forked child.
Fixing that limit ought to be trivial (and making it dynamic based on
the config file limit also easy), although how exim behaves in a
situation where it has huge numbers of incoming connections may be less
easy to characterise.
Awaiting Marc's patches (or at least a bugzilla entry).
Nigel.
