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'
2008-10-20 16:02:50 - unknown (126.96.36.199) --> mail

* From above, the record show mail --> living.com (18.104.22.168]: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 (22.214.171.124) ?

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