Possibly. But I don't think it would bother eximstats. Easly checked.

One of the reasons I suggested generating a message ID 'early' instead of using
PID, was that *AFAIK* all the 'tools' already accomodate that format.

PH pointed out that it would not be wise to do that.

Though not specified, reflection says that one of the reasons might be that the
'convenience' of being able to track the same ID from 'connect' through final
delivery may be offset by making it a bit more difficult to separate messages
that traversed the entire cycle from mere arrivals that were rejected, early-on,
yet carry the same sort of number as if a message had been handled.

TANSTAAFL.
