A Perl CGI script trio, Postfix SMTP Monitoring Solution, tracks the SMTP queue for monitoring purposes.
In my quest for a reliable web-based solution for monitoring my Postfix SMTP relay, I came across these Perl scripts, which proved to be incredibly effective. I was able to use the three simple Perl scripts with Sudo to achieve the desired functionality.
I believe that these scripts can help many people, which is why I'm uploading them to share with others. The installation process is incredibly straightforward. It involves placing the three .cgi files into your webserver's cgi-bin directory and modifying your /etc/sudoers file as instructed in the README file contained in the tarball.
Overall, I highly recommend this solution to anyone looking for a reliable and easy-to-use way of monitoring their Postfix SMTP queue. It's an incredibly useful tool that has helped me tremendously in my day-to-day operations.
