Steve Walsh and David Bell have stated that the amount of spam getting through 
has increased since greylisting was disabled.

I never claimed that greylisting is a waste of time, I use it on my own mail 
server!  But it doesn't seem to provide any benefit for a closed list (IE one 
that only members can post to) if the server also ensures that mail isn't 
forger.  So if SPF was correctly implemented to stop the forged mail from 
James Purser then greylisting wouldn't be needed for the lists.

But greylisting would still be good for all the other addresses.
