[Sussex] Neat MTA trick

[Alan F]

Had a thought this morning about another way to curb the deluge of spam 
I get :)

I have now setup Postfix and BIND so that mail sent to any subdomain of 
my domains is accepted and sent to my maildir, the advantage being that 
if an address gets abused I can blackhole it with an MX record, so my 
MTA/spam/antivirus doesn't have to deal with it. Now that I've started 
using it, should be interesting to have a clear idea of where my spam 
comes from... As you can see, I've tried this for my SLUG subscription 
(I've always had a suspicion that my address got harvested from the 
lug.org.uk archives...)

Oh, and before anyone says anything... I'm sure you could do the same in 
Exim :P

Better get back to studying!
