Two of the great things I have gleaned from this list are:

1. Greylisting is reported to stop upwards of 80-90% of the spam from
   even coming in the door.  The downside is the likely delays imposed
   on the rest of the mail, maybe in terms of hours.

2. Spammers seem to be attracted to secondary MXs.

This morning, in the shower (where many great ideas are born), it
occurred to me that if one combined the two concepts, i.e. implement
greylisting on (only) the secondary MX server, one might get all the
benefits with no downside.

Have I missed something?

Cheers,
