Further testing, showed this event happening again, this time it was my account. I am running the zimbra desktop, on a MAC and a XP machine, side-by-side, comparing the inbox. The Mac version, had the issue today. The debug log from the mac version, shows that the message was downloaded at 1:33 (see bold log entry). 45 minutes later, the email still does not show up in the inbox. It finally showed up after I restarted. This seems to be a major bug! The desktop version on the XP showed the email at the appropriate time along with the web version.
