I've installed zimbra ver. 5.0.18 on ubuntu 8.o4 and all run well...
but.. the users haven't founded there any confirmation receipt...
so I decided to upgrade ver 5.0.18 to 6.0
Ohhh there I found receipt BUT a surprise....
when I add an account to retrieve via pop3 a mail from an mailbox
i recieve this error:
Error on external account
leaving messages on server requires support for UIDL
Have an idea how to resolve this problem ???
In previous version there was any problem !!!!!
