In Nov we updated OpenSSL due to latest security alerts, and at the same

From this day, the graphs charting the number of smtpd processes have gone
from ~100 to about ~500. So it is definitely a recent change we did, that
made something worse.
I have noticed that if I setup the L4 to just do the health-checks, but not
pass through any emails, the amount of smtpd processes balloons to ~1000,
then shrinks down to a stable ~400.
They are all idle, waiting for a timeout. Presumably there is some process
reuse in Postfix to save on the forks?
just fix clients not proper closing connections
