I have several monit 5.4 with their mailserver set to mx1.domain.com mx1 runs postfix's postscreen and is dropping the monit smtp clients with "PREGREET 20 after 0" that's "after 0 seconds", meaning monit smtp client is connecting to port 23 and immediately starts sending, when it should wait for mx1's SMTP greeting. That's why the log line is a PREGREET violation. The "20" means mx1 received 20 characters before mx1 could send its SMTP greeting. As a result, we aren't getting monit alerts and will have to whitelist all the monit IPs so the pregreet filter doesn't drop them.
