[Exim] ETRN

Hello all,

A quick question for you all.

Is there a sensible way to limit the number of ETRN's that are run in
the same way that you can limit the maximum smtp connections?

It is my understanding, and this appears to be backed up by the
Specification doc that it is not possible to track the process once it
has exec'ed and so no limitations are possible.

Note, that i want to limit the number of ETRN's that exim will handle
as a total, not in the smtp_etrn_serialize sense.

Thanks very much.
