Greylisting doesn't cause any real issues unless your setup is badly broken If you're trying to make a point then it's not working ...
It does. Believe me. ISP-A is greylisting mails from ISP-B and those mails will be deferred by only 10 minutes. Over a while customers of ISP-B will wonder why mails take more than 10 minutes to be delivered and postmaster will wonder why his Qs are getting bigger and bigger. It is not hurting that much, but if you can fix it by creating an IRT, you will probably do. Thanks, Tobias abusix.org
