Hello, I like to ask about a documented limitation (http://www.postfix.org/CONNECTION_CACHE_README.html#limitations)
"For this reason, the Postfix smtp(8) client always closes the connection after completing an attempt to deliver mail over TLS." I'm concerned becaus I see increasing traffic delivered via TLS. It is true that now /every single message/ require TCP connect, TLS Handshake, message transmission and TCP close? So SMTP Session caching don't happen anymore? Given a sending server handle 3000 messages per hour to a specific destination that use DANE. Virtually every 1-2 seconds the server open and close a connection. Why shouldn't it be possible to recycle an established connection for multiple message? I only like to /understand/ the above "this reason" ... Andreas
