One word of warning: the example greylist.pl is known to have several race conditions (file-locking bugs) that can corrupt the database. It's also fairly inefficient. Having said that, for low-volume mail servers it still works OK... generally its problems only show up under high volume. -Adam

I finally was inspired to set it up this morning which took about 45 minutes. Seems to be working well but to early to say for sure.
