Whenever the delivery status of a mail message changes, sendmail logs the event and includes the stat= to specify why the change happened . For example, a mail message might initially be queued because the recipient's host was down: stat=queued Later it might change again because it succeeded in being delivered: stat=Sent (HAA03001 Message accepted for delivery) In transmitting a mail message via SMTP the stat= will include the actual text that the other host printed when it accepted the mail message, as shown earlier. But in delivering locally, the stat= is more succinct: stat=Sent In the case of bounced mail the stat= will show the reason for failure: stat=User unknown The stat= syslog equate is included only in recipient records. |
