I have refused greylisting for a long time for that exact reason.
However the setup Pierre Habouzit describes does not delay most of
legitimate mail. Frankly, the remaining delays are sporadic and one can
live with them.

I'm applying greylisting if one of these conditions is met:
      * the incoming IP is listed in a DUL;
      * Exim sender/callout fails with a fatal error.
This setup has considerably reduced both the load and the amount of spam
on the server. However I still have to deal with @debian.org spam with a
less and less efficient (and more and more cpu consuming) bayesian
filter, as it cannot be filtered out this way.
