Is there something reasonable, consistent with administrator
expectations, that Exim could do on start-up on Solaris to either change
or report on suspicious limits?

Is this the same as the per-process RLIMIT_NOFILE but capped within the
zone? Is there something equivalent to getrlimit(RLIMIT_NOFILE, ...)
which could be used to get the limit?

If a default install is likely to cause issues, I think it would be best
to log something on start-up, and perhaps show the warning with "exim
--version" (aka "exim -bV") too. Logging the anomaly but not attempting
to override whatever the sysadmin has done seems, to me, to be the best
approach, but I'm not a Solaris admin.
