Hello,
it seems that there are sporadic errors and postfix doesn't respond fast
enough. If the situation is expected, you can set monit to alert only when the
error is more solid (few consecutive cycles):
if failed port 25 type tcp protocol smtp with timeout 15 seconds for 3
cycles then alert
Regards,
Martin
