I've imported a great deal of messages from the old IMAP server into the new Zimbra server that we are testing. Works fine, except for that messages sorted by date in the Zimbra web interface seem to be all sorted wrong. It seems as though the messages are sorted based on some date other than the date the messages were sent. I think Eudora has this behavior as well, while a lot of other email clients display messages based on the time the message was sent based on the email header. Is that the situation or am I looking at something wrong?

If what I describe is correct, wouldn't it be a good idea to include an option in user options for:

Sort messages by date received
Sort messages by date sent

What do you guys think?

Thank you.
