Optimizing for connection reuse since the overhead of creating connections is actually high for us. So we want to send as many messages as we can over a single connection before closing it.
So do that. When you have no more messages to deliver, close the connection.
Naturally we don't want to cause unrest within the ecosphere by keeping connections open for too long.
When you don't have any more mail to send *at that time* close the connection immediately after the final OK from receiving system. Leaving it open just because you might have more mail later ties up resources on the recipient's side with zero benefit to the recipient. If everyone did this, it could turn into a form of DDoS.
Agreed, but when you are sending high volumes of email, optimizing the opening of a connection and reuse of a connection is worth us investigating.
And when you're finished with the high volume, close the connection. If you have more volume later, re-open it.
