Found /usr/share/logwatch/default.conf/services/sendmail-largeboxes.conf and/usr/share/logwatch/scripts/services/sendmail-largeboxes... that's what I get for only looking in /etc and its subdirectories... had previously tried updatedb and locate and got nothing but I think that I must have misspelled something in the locate command line.
Anyway, all fixed... thanks... :-)
