Hi Meaulnes,
    
    It would be a good idea to add the IP of the sending hosts that you've
    got problems with to that list.
    
    It appears that host is not re-queuing emails within a reasonable time
    if the delivery had been refused with a tempfail.

We have had to stop using greylisting unfortunately because a lot of the big players (Microsoft, Google etc.) are using pools of servers and when mail retries it comes from a different server in the pool (and different IP as a result) each time and sometimes it can take several hours before mail finally gets accepted. It is a shame because greylisting does cut down a lot on the spam, but customers started complaining!

Regards

Colin
