You can disable connection caching, globally or for specific sites. Or you
can let the connection be dropped and make a new one. Nothing wrong with
a dropped connection from time to time... Postfix will try the next MX
host. Postfix does not have a numerical connection re-use limit. Rather,
the limit is a time-limit, because this exhibits (much) better behaviour
when delivering to a mixture of fast and slow servers.

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
