Purpose

maillog2db is a golang program designed to monitor your postfix maillog and push log entries to a mysql database. maillog2db captures the following data from postfix logs:

• Raw log entries are inserted into a single table
• Messages and delivery queues are split and tracked among multiple tables
• Connecting Clients are tracked.

Please create a github issue or submit a pull request if you would like to see the data parsed/handled in any other way, and we will consider making any adjustments.

Example Usage

Once you have the binary available either pre-compiled or source-compiled, usage is as follows (assuming installed under /opt/maillog2db):

/opt/maillog2db/maillog2db -dbhost 10.10.0.1 -dbport 3306 -dbname maillog2db -dbuser maillog2db -dbpass MySecretPassword -maillog /var/log/maillog

Once the binary is started, it will parse any existing entries and watch for any new ones.

for a full list of CLI options, use the following:

/opt/maillog2db/maillog2db -h

Database Schema

The database schema is automatically created by the program upon startup. ensure your database user has CREATE TABLE permissions on the database.

Logging

The program log file by default is placed next to the binary location (ex: /opt/maillog2db/maillog2db > /opt/maillog2db/maillog2db.log). If you would like to change the logging location, simply supply the -logfile CLI switch:

/opt/maillog2db/maillog2db -logfile /var/log/maillog2db.log

Build and run with docker

To run program as a daemon you can use docker. To build docker image:
