        -- If desired, mark the email as SEEN.  There are two
        -- ways to do it:

        -- 1) Set the flag directly by using the sequence number
        -- Indicate that we are passing a sequence number and
        -- not a UID:
        DECLARE @bIsUid int
        SELECT @bIsUid = 0
        -- Set the SEEN flag = 1 to mark the email as SEEN,
        -- or set it to 0 to mark it as not-seen.
        EXEC sp_OAMethod @imap, 'SetFlag', @success OUT, @i, @bIsUid, 'SEEN', 1

            EXEC @hr = sp_OADestroy @imap
            RETURN
          END

        -- 2) Alternatively, we can use the email object.
        -- When an email is downloaded from the IMAP server
        -- Chilkat will add a "ckx-imap-uid" header to the email.
        -- This makes it possible to know the UID associated with
        -- the email.  (This is not the sequence number, which may change
        -- from session to session, but the UID which does not change.
        -- The SetMailFlag method is identical to SetFlag, except
        -- it gets the UID from the ckx-imap-uid header.
        -- For example:
        EXEC sp_OAMethod @imap, 'SetMailFlag', @success OUT, @email, 'SEEN', 1
        IF @success <> 1
          BEGIN
            EXEC sp_OAGetProperty @imap, 'LastErrorText', @sTmp0 OUT
            PRINT @sTmp0
            EXEC @hr = sp_OADestroy @imap
            RETURN
          END

        EXEC @hr = sp_OADestroy @email

        SELECT @i = @i + 1
      END

    -- Disconnect from the IMAP server.
    EXEC sp_OAMethod @imap, 'Disconnect', @success OUT

    EXEC @hr = sp_OADestroy @imap


END
