You can keep your clients spam-free without greylisting; We have a Postfix +
Popfile + spamassassin combo working with 99.94% efficiency.

Popfile classified all but 52 emails correctly out of the last 94,009. (since
the stats were last reset, 2.5 months ago)

IMHO greylisting is a temporary solution, and spammers will evolve to work
around it.

A well written bayesian filter will evolve with the spam, and keep the high
efficiency, as ours did for over a year now. The amount of spam has been
steadily increasing for ages, but POPFile was able to keep up with it, and it
keeps improving with time.

A good solution does not have to hurt anybody (...but the spammers :-).

Just my 2 cents.
