How to get statistics about the performance of your mail server

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).
Enable qplogsumm
qplogsumm.pl is disabled by default. Enable it with
config setprop qpsmtpd qplogsumm enabled signal-event email-update
Force first log rotation
qplogsumm.pl only updates its statistics when the qpsmtpd log file is rotated. This can take several days on a moderately busy server, and might take weeks or months on a small, home server.
You can force a rotation of the qpsmtpd log files in order to generate initial data in [[tt]/var/log/qpsmtpd/state[/tt] using
kill -ALRM `cat /var/service/qpsmtpd/log/supervise/pid`
Potential Problems
qplogsumm.pl will completely lock all in-bound email if [tt]/var/log/qpsmtpd/state[/tt] is missing when multilog attempts to rotate the qpsmtpd log file. This can be resolved using
touch /var/log/qpsmtpd/state sv restart /var/log/qpsmtpd

qplogtail
qplogtail is a script intended to help monitor /var/log/qpsmtpd/current and extract a concise but meaningful display of what the server is up to.
qplogtail extracts 6 kinds of information:
- Normal connections:
28545 Accepted connection 4/30 from 86.139.2.73 ... - Errors in violation of Instances:
5146 Too many connections: 40 >= 40. Waiting one second. - Errors in violation of InstancesPerIP:

If you have the connection_time plugin installed, you will also get:
