        This is called connection caching, and it has been a point of
some previous contention on this list. In particular, I am rather
sensitive to this issue.

        My understanding is that the current solution is to set up a
separate transport for each mail server (or set of mail servers) for
which you wish to make connection-caching happen more often.
However, you'd probably do better by searching through the archives
of the list to confirm.
