my check on postfix and the output in /var/log/maillog are below. I don't expect some of the behaviour
a) monit appears to connect to postfix twice for each cycle
b) the sequence is connect, lost connection, disconnect, surely monit connects and then disconnects so the lost connections are an error postfix or monit
check process postfix with pidfile "/var/spool/postfix/pid/master.pid" start program = "/etc/init.d/postfix start" stop program = "/etc/init.d/postfix stop" if failed host localhost port 25 type tcp then restart
