Last weekend, we just upgraded zcs6.0.4 Network edition to zcs6.0.7 Network edition on Ubuntu 6.06 64bit server.
After upgrade, we observe some emails from a few internal users are put in Junk folder in recipient's email account. We tried to mark the sender is safe in Zimbra-Outlook, but we still see the emails are put in recipient's junk folder.
Anyone can help? Really appreicate!
