I thought about doing it with that part of the address using aliases, 
but I'd have to set one each time I decided to use a new address, and 
it'd still hit my MTA. But I suppose some people don't have such easy 
access to their zonefiles.

Btw Jon, if anyone over at nixhelp was wondering why I've been away for 
the last few weeks (or not), it's because of exams, the last of which I 
have on Monday... So I'll probably be back sometime next week :)

I was just taking a break, honest :)
