I have Zimbra installed on an Ubuntu system (Version zcs-4.5.-_GA_612.UBUNTU6.tgz). Everything is working great except the zmtrainsa that runs each night. The zmtrainsa dies each night with the following messages (one for each email that has been sent to it):
 WARN: exception occurred fetching message
java.io.IOException: HTTP GET failed: /firstname.lastname@example.org/?id=895ebe5a-c7fd-41c7-a036-de45a46e8371:300: 403: permission denied: you do not have sufficient permissions
Any ideas or hints?
