/smilie mode on Well... there is another severe problem with using greylisting. It breaks conventional email. I have not seen this stated yet on the list, yet it is potentially very very damaging to email as we know it...! Take for instance, the other day. I was just happy, relaxing, sending 28.3 million emails out to some dear friends of mine who -I believe- wanted to know what I've been up to and what I currently sell. And whaddayaknow, I got hundreds of thousands "Undelived"-status, as was shown in my emailprogram. And all that due to greylisting, no less. So. This has got to stop !! /smilie mode off So are there -for us poor woody users out there- any alternative means to deploy greylisting ? For instance, does only postfix have greylisting or do other MTAs have (or plan to have) greylisting ?
