Postfix is a fine example. You just define the table and the query to either have an until column, or have a column with the timestamp of when the entry was added and have the query ignore rows which are older than some given time. And with postfix, using its sql proxy capability, using a sql backend is fully performant.
So, you agree, MTA's do not implement this functionality. It's obviously possible to make it happen through shell scripting, database tricks, etc., but the point was that if this was commonly desired, then MTA's would be supporting it directly. It isn't commonly desired, most people just block "forever." It never ceases to amaze me how technical people so often easily miss the point. :-) ...
