After the release of the FFMPEG Installer, we are releasing a new WHM Plugin to log all mails sent through the server using the sendmail binary. You can see the logs inside the WHM and identify the the spammer instantaneously.
Details regarding the Plugin is available at : http://admin-ahead.com/sendmail_logger.html
All instructions pertaining to the install is available at the above link. Once installed, you can see a new link to the “Sendmail Logger” inside your WHM under the Plugins Section.
Please Note: For the plugin to work; you will need to recompile php with “Mail Headers” enabled. You can do this via easyapache.
Tested on CentOS 4/5 i386. Should work on others, but any update would be great.
