Email Statistics
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
Contribs & Addons
Brian Read's spamfilter-stats-7.pl
Brian Read's mailstats.pl script analyzes your qpsmtpd log files and sends a daily email to "admin" summarizing that day's email activity.
Download & Installation
wget -O /etc/cron.d/mailstats.cron \ http://mirror.contribs.org/smeserver/contribs/bread/mailstats/mailstats.cron wget -O /usr/bin/spamfilter-stats-7.pl \ http://mirror.contribs.org/smeserver/contribs/bread/mailstats/spamfilter-stats-7.pl
WARNING: Make sure that these files are accessible before executing the above commands! If you are unable to access http://mirror.contribs.org/smeserver/contribs/bread/mailstats/ the above commands will create empty files, overwriting existing versions.
Configuration
The latest release (v0.6.15) supports several SME database options:
- Create the service
config set mailstats service
- Status
config setprop mailstats Status ("enabled"|"disabled")
- Column Header entries are created and set to "yes" if a non zero count is detected (they may not exist before). "Yes" means that that column is then always shown. If you delete the entry or set it to "auto" then it will only show if a non zero occurs again (and then get set to "yes").(enable, supress or only show if nonzero)
config setprop mailstats <column header> ("yes"|"no"|"auto")
- QpsmtpCodes
config setprop mailstats QpsmtpdCodes ("enabled"|"disabled")
- SpamAssassin Rules
config setprop mailstats SARules ("enabled"|"disabled")
- JunkMailList
config setprop mailstats JunkMailList ("enabled"|"disabled")
- SpamAssassin Rule Percent Threshold for report cutoff
config setprop mailstats SARulePercentThreshold (0.5)
- Email to send report
config setprop mailstats Email (admin) - email to send report
In older versions, the email recipient is specified in the spamfilter-stats-7.pl file, using:
$opt{'mail'} = "admin";
which will deliver email to the local 'admin' account on your SME server. Configure email forwarding in server-manager::Collaboration::Users::admin to deliver the emails to another location.
Handling @*.u Logfiles
Multilog occasionally generates log files that end in ".u" instead of ".s". The multilog manual says this:
- .s: This file is completely processed and safely written to disk.
- .u: This file was being created at the moment of an outage. It may have been truncated. It has not been processed.
The latest version of mailstats.cron will process "@*" and "current", so will catch all log files. Earlier versions only processed "*.s" and "current".
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 5 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:
5320 hosts_allow plugin: Too many connections from 212.100.229.201: 6 > 5Denying connection. - 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 - Messages queued for delivery:

Each smtp transaction will generate two lines of output containing:
msgid remote_ip x/40 msgid remote_ip dispostion details
