Email Statistics

How to get statistics about the performance of your mail server

Built-In Statistical Reports

Server-Manager

Some email statistics can be seen from server-manager under "Administration", "Mail log file analysis"

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

qplogtail extracts 5 kinds of information:

1. Normal connections:
   28545 Accepted connection 4/30 from 86.139.2.73 ...
2. Errors in violation of Instances:
   5146 Too many connections: 40 >= 40. Waiting one second.
3. Errors in violation of InstancesPerIP:
   5320 hosts_allow plugin: Too many connections from 212.100.229.201: 6 > 5Denying connection.
4. Messages blocked by any qpsmtpd plugin:
   15751 logging::logterse plugin: ` 82.210.181.241 241-pra-6.acn.waw.pl 241-pra-6.acn.waw.pl <Glasteinzhza@ask-it-here.com> dnsbl 903 http://www.spamhaus.org/query/bl?ip=82.210.181.241 msg denied before queued
