Some variants of broken smtp configurations will choke on greylisting,

and spamd doesn't really have much in the way of smtp smarts beyond

what it needs in order to waste spammers' time.  If somebody important

is unable to deal with greyliting, you will probably need to whitelist

them.  And yes, those toy relay checkers that do not check if the

message gets delivered do tend to think spamd is an open relay.  That

and some spammers' tricks will swell your greylist a bit from time to

time, but I don't really see that as much of a problem in real life.
