We migrated to zimbra recently. It went reasonably well. We do have an annoying problem though.
The problem is this: all imported messages are displayed as though I received them, even the messages sent by me to someone else. Now, I think this is some kind of itemflag as moving the message to the Sent Items folder doesn't change anything. The 'from'-address also changes nothing. Please note the following example (pietje is an alias of zimbraldap, so I'm sending to myself):
vincent@lt-vam:~$ telnet mailserver 25
Connected to mailserver.
Escape character is '^]'.
220 mailserver.domain ESMTP Postfix
250 2.1.0 Ok
250 2.1.5 Ok
354 End data with <CR><LF>.<CR><LF>
From: Zimbra MigrationLdap <firstname.lastname@example.org>
To: Frits Spits <email@example.com>
Subject: Sent item test
Een leuke test voor sent items...klopt dit?
250 2.0.0 Ok: queued as 304CE14819D
So, when I log into my webmail account, I see a From-column with zimbraldap in it. I expected to see pietje as the To-address.
Using this example, I think 'sent by me' is a message flag. Can anyone help me? I need to change this for about a hundred thousand emails.
