I think you're probably right here.  I peeked at my logs dating back to May
30, and there is one address that I use on a regular basis - albeit very
discretely - that gets almost no spam at all.  Methinks I shall use that one
when I need something in a hurry, either turning off greylisting on demand,
or killing it altogether for that user (postgrey has a per-recipient
whitelist as well for them as don't want it at all).  

What's also funny in a wry sort of way is the sheer number of creative
different ways spammers try and get through your nets... I have seven
different legitimate accounts on this one server, scattered across four
domains.  In that same since-May-30 review, they tried *seventy-five*
different combinations of random.stuff at do.main, some loosely based on
legitimate accounts, some mashups of other stuff, some just random garbage.
No idea what or even if they're thinking.
