MTA Log Analysers

ExiBomb Mail

ExiBomb is a system designed to monitor email traffic on an Exim-based MTA server. The interface is written in PHP. It reads the mail logs in a tail method and stores all relevant data in a MySQL database.The script reading the logs was developed in Perl. - UNIX Sendmail Log Analyzer

Sawmill is a UNIX Sendmail log analyzer (it also support 686 other log formats). It can process log files in UNIX Sendmail format, and generate dynamic statistics from them, analyzing and reporting events. Sawmill can parse UNIX Sendmail logs, import them into a SQL database (or its own built-in database), aggregate them, and generate dynamically filtered reports, all through a web interface. Sawmill can perform UNIX Sendmail analysis on any platform, including Window, Linux, FreeBSD, OpenBSD, Mac OS, Solaris, other UNIX, and more.

Sawmill stores the following fields in its database for UNIX Sendmail, generates reports for each field, and allows dynamic filtering on any combination of these fields:

  Field   Internal Name
   from   from
   to   to
   server   server
   daemon   daemon
   mailer   mailer
   stat   stat
   class   class
   priority   pri
   protocol   proto
   relay   relay
   reject   reject

Sawmill stores the following numerical fields in its database for UNIX Sendmail, aggregating them and including them as columns in most reports:

  Numerical Field   Internal Name
   messages   messages
   size   size
   delay   delay
   xdelay   xdelay
   number of recipients   nrcpts

Sawmill also supports 686 other log formats; see Sawmill Features for a list containing UNIX Sendmail and all the other supported formats.


Anteater is a log analyser for MTA logfiles (such as those produced by sendmail and postfix). The tool is written in 100% C++ and is very easy to customize. Input, output, and the analysis are modular class objects with a clear interface. Currently, there are modules for reading the syslog format of sendmail and postfix that do up to eight useful analyses and write the result in plain ASCII or HTML, to stdout or to files.
