    Default Imap dropped in 5.0.1

    I upgraded from 4.5.8 to 5.0.1 and my imap clients have a problem with their connections to my server in this new release.

    There are some times, when the Outlook checks the email via imap, the connection dropped and show

    "IMAP4rev1 server terminating connection"

    This problem occur with ssl connection too.

    And this is my /opt/zimbra/log/mailbox.log

    Default

    That indicates that your Outlook client dropped the connection without a LOGOUT. The stack trace was the Zimbra server trying to write info to the socket that Outlook had already closed.

    Is there any way for you to get the protocol-level trace from such an Outlook connection?
