Really? I get a metric butt-ton of spam every day to this address.
I'm sure I get sent a lot of spam (though I don't know for sure -- see
below). But I don't think much of it comes from Usenet harvesters any
more.
Right now it simply filtered by address straight into my recycle bin,
I suppose if it ever becomes burdensome or starts to choke my
bandwidth I'll tell my mailserver to bounce it :)
Don't do that. Get your mailserver to /reject/ spam during SMTP with a
5xx code. Bouncing spam is really bad because it implicitly assumes
that the envelope sender address is good. Spam rarely has a valid
envelope sender. If you're lucky, the envelope sender is simply
invalid, and you'll end up with a double-bounce when your mailserver
finds out. If you're unlucky, the envelope sender is a /valid/ address
from the spammer's list and some innocent victim will end up receiving
your bounce (this is called `backscatter').

Whoops, I forgot 'bounce' has a clear meaning in the world email, I
meant reject. Having suffered plenty of backscatter back in the day I
wouldn't want to wish that on anyone. Thankfully I haven't had any of
that in a few years now. I guess a lot more people are using Domainkeys
and SPF these days.
