ouch
In some cases the spammers pick up a bounce and remove that email
address. Why send stuff to something that doesn't exist. In the case of
zombies it's annoying yeah. Oh well, it was something I wanted to try.
You do have a good point.
However, dropping it to dev/null isn't always a good idea, especially
since it's user configured. Having something automagically empty the
user's spam folder is much better. :)

Progress isn't made by early risers. It's made by lazy men trying to
find easier ways to do something.
