> Dear List:Following is one line from the postfix logs. --------------------------------------------------------------------------------- May 2 10:05:44 dnserns.isac.gov.in: postfix/smtpd[1536248]: NOQUEUE: reject: RCPT from unknown[72.3.227.162]: 502 5.7.1 : Helo command rejected: Host not found; from= to= proto=SMTP helo= ------------------------------------------------------------------------------As per the above example, as we have used the policy of reject_unknown_hostname and the mails where introducing host is not resolvable are getting rejected.Now, when the users complain that, some mails are not getting delivered to them, we go through logs and find the reason like one above and inform that this is due to this and tell the sender also to look into their configuration and resolve the issue. And most of the times, they solve the issue.But, when they solve, I want to know what their system is now introducing itself as. How can I make it part of log? Can it also b
ecome part of Mail headers?Regards, ANANT.
It is already known. You should see logs as such:
