Hello, I am trying to accomplish a connection cache for TLS. I set it up for non - TLS connections and it works just great.
Then i tried to look at the TLS connections. First i enabled the session cache with smtpd_tls_session_cache_database, that works great as well. The problem is, that each email to same destination is sent via new connection. I also am aware of limitation of connection cache which says The Postfix shared connection cache cannot be used with TLS, because saved TLS session information can be used only when a new connection is created (this limitation does not exist in connection caching implementations that reuse a connection only in the process that creates it). For this reason, the Postfix smtp(8) client always closes the connection after completing an attempt to deliver mail over TLS. but the part in the brackets makes me wonder for a possibility, that if i keep sending emails over same smtp process, it could be possible. I looked everywhere, but was not able to find anything remotely helpful. Could anyone point me to right direction ? Thanks you and best regards
