I changed my own opendkim server's config,

        SignHeaders
        message-id,date,from,reply-to,mime-version,to,subject,content-type,content-transfer-encoding
- #OmitHeaders header1,header2
+ OmitHeaders date

then restarted opendkim. re-sent the external email, checked the
headers of the received, forwarded message, and *still*,

        ...
        Authentication-Results: zimbra.locusetest.net/E3F32606AF;
        dkim=pass
                (2048-bit key) header.i=_at_gmail.com header.b=IES7eK10;
                dkim-adsp=pass
