True, but unless you're using lazyaw this would only apply to spammers that are
using the same touple as previously seen. Such repeated use of the same source
IP, MAIL FROM: and RCPT TO: will eventually bypass a greylist anyway.

That said in my experience very few spammers will retry with the same touple,
ever. (I run with a greylist period of 1m, and this works very well)
