I've been lax in back-porting the MUC (multicast/unicast cache) API to
milter-gris and milter-ahead. milter-sender was discontinued June 2009,
 so will not be updated. So far there is no set schedule for this work.

The comprehensive product, BarricadeMX, has the shared cache support for
all the techniques is supports: classic grey listing, grey content
listing, call-ahead, call-back, etc.
