This would also be unwise given that mailq/postqueue -p can return
incomplete results when the number queued files gets large - or more
accurately that there is a limit to the amount of data mailq will show
and thus it isn't specifically a message count limit.
On Linux systems I use an inotify enabled kernel (>= 2.6.13) and track
the events via daemon/db. I then query the daemon when I need counts.
You could do similarly on systems that provide an inotify-like feature.
Cheers,
Bill
