1 - Please show command output of "postconf -n | grep postscreen". This contains the time that postscreen is configured to wait, and this may differ from what you show with "cut and paste" from main.cf. 2 - Please report the postscreen greeting delay as measured by connecting to the network port. 3 - Is this time substantially different from the time specified in (1)? If it differs, is perhaps Postfix running in a virtualized environment? Wietse
