I'm going to have to disagree with Ralf here. I'm assuming by "deep" you
mean how many messages were in the queue at any give time. Given that...

If you have a known starting point, you can simply process the logs and
keep track of it in your script. There are a few stumbling blocks, that
the script writer needs to be aware of such as deferred messages that are
returned and not logged (fixed in a recent snapshot).

YMMV, but this works for me on our FreeBSD boxes...

#!/bin/sh

egrep $1 /var/log/maillog | cut -d":" -f4 | sed 's/ //g' > /tmp/mytmp.$$
egrep -f /tmp/mytmp.$$ /var/log/maillog
rm -f /tmp/mytmp.$$
