I´d like to bring up an old subject again since browsing the forums I haven´t found any solution. Zimbra doesn´t support POP3 servers that don´t support UIDL. This affects my own 3 GMX accounts and other mail hosts of many other would-be zimbra users aswell.
I currently use Opera M2 and Outlook. I have also tried Evolution, Revolver and Spicebird. Fetching mails from GMX and leaving messages on server was never a problem.
The problem has been documented 6 months ago. Don´t you consider this a serious issue? Does the admin team plan to solve this any time soon or should I uninstall zimbra which I like a lot otherwise?
