Yes, thanks for your time.
Have upgraded all relevant machines to postfix 2.8.2
Apparently cached smtp connections on the sending server (to the
popper) are brought down early if there is nothing to send.
Also apparently there is a minimum of 5 connections, had
smtp_destination_concurrency_limit set to 1 just for yuks, and still got 5
or 6 established according to netstat. conn_used never went above 17 even
though I had the time limits set to 3000, again just for yuks.
Beyond that its definitely caching!
Anyhow is there a way to get postfix to display the remote server name
in the process list of smtpd and smtp's. I miss that from sendmail.
Thanks in advance for your time, and pointers to RTFM.

Is there a way to set a mail server to only open one connection
to another, and send all mail over that one connection keeping it alive?
/etc/postfix/main.cf:
smtp_destination_concurrency_limit = 1
smtp_connection_cache_on_demand = yes
There was a typo in the URLs:
References:
http://www.postfix.org/postconf.5.html#smtp_destination_concurrency_limit

Is connection caching already available in Postfix 2.1.x ? In the
README 2.2 is mentioned but not sure if this is because of the changes
or because it is the first release with connection caching.
From the OP:
"Running FC5 Postfix 2.1.5, Qpopper 4.x"
Surely, they can RTFM the references, and see what features
are available at what Postfix release level.
