This plugin allows you detect and refuse bogus bounce messages, which these days are often a source of spam.

In this plugin a "bogus bounce" is defined as a bounce message which is addressed to multiple recipients.

This plugin is a little unusual in that the checking occurs in the data-handler. This obliviates the need to pass state around when testing for recipients, as would otherwise be required.
