From the Zimbra Inbox I compose and send an email. Zimbra indicates that the message was sent. However, the message is never delivered. I tried sending an email to myself (ie the local Zimbra account) and to my gmail account with same result.
I have setup Zimbra as a secondary mail server per instructions in Split Domain - Zimbra :: Wiki. I implemented the configuration changes to make Zimbra a secondary mail server and to avoid mail delivery loops.
I notice the following linesin the zimbra.log:
Jun 2 17:21:02 zmail postfix/qmgr: 156FE36130: from=<firstname.lastname@example.org>, size=559, nrcpt=1 (queue active)

Thank you in advance.
