I just received an email that appeared in Outlook as a raw message, with all the headers displayed and the mime message completely unformatted.
Upon checking I saw the message had no recipients in the To; or CC: fields - it had been sent entirely using BCC.
I just tested sending a message with myself as the only recipient in the BCC field and saw the same effect.
Can anyone else emulate this? Or does anyone else know if the issue has been raised before and resolved in a later version of the zimbra or the connector? We're using 5.09 currently.
