This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix (e.g. using amavisd-new). These graphs can be accessed with a browser, whereas pflogsumm (“Postfix Log Entry Summarizer”) can be used to send reports of Postfix activity per email.

In the following I will describe how to install and configure Mailgraph and pflogsumm on Debian Lenny.

I do not issue any guarantee that this will work for you!

1 Preliminary Note
In this tutorial my Linux system has the IP address 192.168.0.100 and hosts the web site http://www.example.com with the document root /var/www/www.example.com/web and a cgi-bin directory of /var/www/www.example.com/cgi-bin, and I will send the pflogsumm reports to the email address postmaster@example.com.
