How do we fix the silly configs?  With suggestions for values?

Firstly by contacting the postmaster at the other site with which you are 
having interop problems. If you can point to an rfc like Murray's that may help.

I don't see how your draft reduces the need for this kind of liaison or how it 
can help with your example of a silly one day greylist blocking period.

Ok, I bite, what are your recommendations for:


  Blocking Time:  ___ secs/mins

Short. There's little point in sending more than one 450, to prove the sender 

  Record (sender recording) Expiration Time:  ____ secs/mins/hours/days

Something like a week.

Client:  Retry Frequencies

RFC 5321 has guidelines. You need to try many more than four times!

and I presume the fix means that EVERYONE has to use the same values at all 
servers and clients?

Of course not.
