-// The logic here is:  In order:
-// 1:: If whitelisted, accept.  No greylisting, no spam-checking.
-// 2:: If blacklisted, reject.  No greylisting, no spam-checking.
-// 3:: If good reputation, spam-check it and send it on its way.
-// 4:: If no reputation, greylist.
-// 5:: If bad reputation, ????
-
-// Expanding item 3 to the next level of detail:
-//  3a:: If some domain vouches for this sender-IP via SPF,
-//   then the reputation is bound to the domain.
-//  3c:: If some domain vouches for the message vie DKIM,
-//   then the reputation is bound to the domain.
-//  3d:: If no SPF or DKIM, then the reputation attaches
-//   to the sender-IP.
-
-// Expanding item 4 to the next level of detail:
-//  4a:: If the greylisting database says this message is ripe
-//   spam-check it.  If it's OK, use it to count toward reputation.
-//  4b:: If it is previously unseen or too old, start greylisting
-//   timer from scratch.  Reject with temporary error.
-//  4c:: If it is in the "green" state, let the timer
-//   continue from where it is.  Reject with temporary error.
-
-// Note:  Reputation normally attaches to a domain.
-//  With SPF, the domain vouches for the sender at a given IP address
-//   ... and then the sender implicitly vouches for the message.
-//  With DKIM, the domain vouches for an individual message.
-//  With neither SPF nor DKIM, reputation attaches to the sender's
-//    IP address.  The sender vouches for the message.
-//
-// During greylisting, delay applies to the message.  Reputation
-//  applies to the domain (via SPF or DKIM) or to the server
-//  (otherwise).
-
-
-// If you are a medium-sized operator, such that you have one
-// and only one IP address that ever sends email, and it is a
-// static IP address, then you don't have much to gain from
-// DKIM or SPF.  Attaching a reputation to your domain is not
-// much different from attaching a reputation to your IP address.
-
-// In constrast, if you are a low-budget operator with a
-// dynamic IP address, you benefit from SPF and/or DKIM.
-// Your reputation attaches to your domain, and remains
-// stable even as your IP address changes.
-
-// At the other extreme, if you are a big-time operator
-// such as googlegroups.com, you benefit from DKIM and/or
-// SPF.  Your IP addresses are not dynamic, but they are
-// numerous, so you prefer to have your reputation apply
-// to all your email-sending hosts.
