What's the Sendmail feature called? And does it generate specific log
entries in /var/log/maillog? Could you provide a couple of sample log
lines?

It should be relatively easy to either add another script or modify
the Sendmail script ( /etc/log.d/scripts/services/sendmail - be sure
to use revision control or keep a pristine copy) to Logwatch to parse
specific entries out of maillog and to include a breakdown of them in
your daily Logwatch mails. Or to knock up an additional item in
Cacti/Munin or just use MRTG/RRDTool directly, to generate graphical
representations.
