Hello,
I was curious if anyone had documentation or knew appropriate times to keep
an SMTP connection open and when to close that connection. Would connecting
via telnet to an ISP and watching when that connection closes, be the
source of truth on how long an SMTP connection should be lasting with
5 seconds :)
Really, opening a new connection is normally faster than that, and some
email endpoints might have a limited amount of SMTP sessions, so why hog
them when someone else can use them..
A Polite 'neighbour' would not hold it open 1 second longer than is
necessary...

What are you optimizing for? Connection time/overhead?
It would seem kind of pointless to keep a connection open for 10 minutes to
save 2s of connection time, for example.
Not that we're the best neighbors in this regard, but we don't reuse
connections for the vast majority of endpoints, just th
What are you optimizing for? Connection time/overhead?
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.
Naturally we don't want to cause unrest within the
I suggest “as short as possible” - 10, maybe 20 seconds with no mail?

and we only keep connections open for potential reuse for 30s.
Have you considered turning

Have you looked at the related RFCs? (2821 and 1123 primarily but et

So do that. When you have no more messages to deliver
