The tracing tools on Zimbra only display Message-ID, sender, and recipient. Many of our client or even me 🙂 need to know what the subject from an email that has been sending. A few days ago, my boss found the script that can display subject on zmmsgtrace.
The original script has been modified to display the subject. You can find modification script from here : https://github.com/cdhtlr/Zimbra-Tools/blob/master/trace.pl
To display the subject, you should enable subject information in the log as mentioned in this guidance : adding-subject-and-attachment-information-on-the-log-zimbra. Then, you can replace default zmmsgtrace. Perform the following command as root
cp /opt/zimbra/libexec/zmmsgtrace /opt/zimbra/libexec/backup.zmmsgtrace curl -k https://raw.githubusercontent.com/cdhtlr/Zimbra-Tools/master/trace.pl > /opt/zimbra/libexec/zmmsgtrace
The following is an example on my server
Message ID '2045709166.99.1541433231183.JavaMail.email@example.com' Subject 'Testing Subject on zmmsgtrace' firstname.lastname@example.org --> email@example.com Recipient firstname.lastname@example.org Nov 5 15:53:51 - myzimbra.imanudin.net (10.148.0.3) --> 127.0.0.1:10026 (127.0.0.1:10026) status sent Nov 5 15:53:51 - myzimbra --> myzimbra.imanudin.net:7025 (10.148.0.3:7025) status sent
Good luck and hopefully useful 🙂
