I am using smtp client to send email alert through zimbra.
Some of the recipient claimed that they didn't receive the alert email.
I run the command zmmsgtrace -i/-s/-r/-t to trace the email status.
but I check the log and see:
Message ID '021a01c9328a$6a73f630$2e04f403@schlaptop'

* From above, the record show mail --> living.com (126.96.36.199]:25) but for the 1st and 2nd case, it is mail --> 127.0.0.1 (127.0.0.1]:10024). Why it is different? Why the 1st and 2nd case record not like mail --> c.mx.mail.yahoo.com (188.8.131.52) ?

Can I determine whether an email has delivered to its recipient through the status returned by command zmmsgtrace? Is it accurate?
