qplogsumm.pl
SME 7.2 and later include the 'logterse' plugin to qpsmtpd as well as the 'qplogsumm.pl' statistics script.
qplogsumm.pl updates /var/log/qpsmtpd/state with per-plugin statistics for any qpsmtpd plugin that appears in a qpsmtpd logterse entry each time the qpsmtpd log is rotated.
Sample output here
e-smith-viewlogfiles-1.8.0-4 (released Nov 28 2007) or later will allow you to 'View' /var/log/qpsmtpd/state from 'View log files' in the server-manager (earlier versions conceal all files named "state" - Bug 3416).
Currently, qplogsumm.pl is disabled by default. Enable it with
config setprop qpsmtpd qplogsumm enabled signal-event email-update
