Woah! 64 bytes per address is huge!
I would reckon about 4 bytes total would do it. Seed your random
number generator with the 4 bytes. Then select at random a proxy from your
list and a victim to use as the bogus from address. Use that pair to
spam, say, 1000 people, and then repeat the process.
Yeah, I was assuming 64 bytes, assuming they didn't want to change how
they picked the addresses to spam ;) 64 bytes = [ random seed, email addr
to spam, IP of proxy to use ].
It's *trivial* for
spamware to get past greylisting; the only reason it doesn't yet, is
because it's not yet widespread.
But the combination of graylists, RHSBLs and SPF could pack a powerful
punch.
Hey, that's the SpamAssassin philosophy! ;)
