Another (non-exclusive) possibility is to change some of the message
handling parameters such as smtp_accept_max_per_connection so that only
a limited number of messages can be sent in a single connection, thus
limiting the ongoing use of a connection.

Changing these parameters may have effects (potentially good or bad) on
your overall mail throughput etc and this will depend very much on the
type of usage and loading of your systems.
