<DIV dir=ltr><FONT face=Arial color=#000000 size=2>greylisting is bad and
I will never ever run it. I know of one case where greylisting has very nearly
killed someone. They probably shouldn't have been using email to do what they
were, but thats not the point.</FONT></DIV>

<DIV dir=ltr><FONT face=Arial size=2>greylisting adds an unnecessary delay to
email, and can quite easilly be beaten if a spammer sets his mind to
it.</FONT></DIV></DIV>
