We've been getting several reports of people when downloading email from a 3rd party client (outlook, outlookexpress for sure possible others) using pop they are receiving duplicates email messages in there inbox, sometimes 3-4 copies of the same email. I can view there email through the Zimbra webmail and the duplicates do not exist there. I'm wondering if there is some sort of caching issue somewhere somehow. Wondering if there was a known issue and if there was workaround for the issue. Again this is not widespread but we are starting to hear more and more reports about the problem.
