I use policyd and give my users the ability to optout (or optin depending on the domain settings) of greylisting if they choose. They can do it through a plugin in SquirrelMail so, if they choose, they can turn it off for a few minutes to get "instant" delivery and turn it back on when they are done or just leave it off. It seems to work well enough here. I have to agree with others in this thread that, in general, the more you can safely stop before it hits your filtering system, the happier you'll be. > > I think technologies like SPF have a better futur. I don't know. I've seen too many problems with SPF and mail forwarding from hosting providers.
