My client has an old Exchange 5.5 server without the Internet connector. Since there is no Internet connector, accounts do not have SMTP addresses like email@example.com. When I import mail from this Exchange server into Zimbra 3.0.0_M2_740 and then view the user's Inbox with the Zimbra webmail client, the FROM: addresses are empty. Opening a particular message will show the FROM: address as:
I assume that Zimbra is looking for a fully-qualified email address of the form firstname.lastname@example.org. Since it only finds "Joe Smith", it decides not to display anything.
I have searched the forums and found no other posting relating to this. Has anybody else seen this problem? Is there a workaround?
