No, the contact page Fealiks snagged it from states that unless an email contains a certain word (at the moment it's "spandoozled"), it'll simply sit in Gmail's 'spam' folder for eternity. If the word is present, it'll be forwarded through.
It's a remarkably effective block and it's pretty much 100% effective at stopping bots and such from adding you to their spam lists. It can also be used for signing up for sites and such; I simply check Gmail for the latest email which'll be the activation form or whatever.
It's also good at stopping 14-year-olds with a chip on their shoulder.
