qmail-spp provides plug-in support for the qmail SMTP daemon (qmail-smtpd). It allows you to write external programs and use them to check SMTP command argument validity. The plug-in can trigger several actions, like denying a command with an error message, logging data, adding a header and much more - see documentation for details.
