It seems that PCWorld have included on a CD distributed with the magazine, a piece of software called BounceSpamMail. The user drops the offending message into it and it forges a bounce from postmaster(a)your.domain. Does wonder for the REAL postmaster account when the spammer's dropbox is invalid.
Its only of very limited effectiveness. Very little spammers use bounces and any kind of feedback, in fact, mostly (90%) the fake from header and envelope and use an open-relay.
