Would it be possible to auto-whitelist combinations of sender and IP that have 
been seen before?

Also do we even have a problem that greylisting will solve?  The server does 
SPF checks so anyone who has a SPF record with -ALL won't have their mail 
spoofed.  The server will only accept mail from subscribers so we won't have a 
problem of spam from random addresses being sent.

As far as I recall we have only had a single instance of spam going to the 
list and I don't think that's due to greylisting.
