Any MTA which supports using an sql db as its backend.  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.
