The Postfix connection cache moves file descriptors between processes.
Unfortunately, the OpenSSL library does not support serializing
and de-serializing the SSL state of a live SSL connection.
So at this time, TLS connections are not cached.

There is no cache internal to a single process. That would only
work well with single-destination smtp transports. Otherwise,
there would be lots of cached connections that never get used,
because the delivery agent is talking to someone else.
Since in-process caches would be most-likely misunderstood and
misused, they are not implemented.
