Re: list headers, and filtering rules

You can filter the TZ list quite nicely by using the "Resent-From" header or the presence of tz@lecserver.nci.nih.gov as a recipient. No reason to pollute the subject line.

Indeed. Or otherwise look for the X-Mailing-List header: X-Mailing-List: <tz@elsie.nci.nih.gov> See also http://www.tux.org/lkml/#s3-18
