Recently some of my users encounter problem with their mailbox, they can't receive any mail nor send mail out. When sending mail an error will prompt, "An object with that name already exists.". When sending mail to the affected users, the delivery error mail will indicate that "Permanent message delivery failure (in reply to end of DATA command)".
Any kind soul could help?
** I going to migrate the current 32 bits zimbra to 64 bits version with the reference from Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki . Wonder will same problem occur after I migrate?
Thanks in advance!
