Hi Barbara, Thursday, June 12, 2003, 4:23:32 PM, you wrote: BS> Thanks Sandi. I will do that then. I thought maybe it would organize my BS> stuff better. Barbara Modern internet standards require that mailing lists and discussion lists have certain keywords in the headers of each message. This list contains this in the header of each list message: X-list: pcductape It does NOT conform to the standard, but it's better than nothing. Maybe someone needs to nag the Ecartis/Freelists folks to upgrade. Lyris uses this: List-Unsubscribe: <mailto:leave-researchbuzz-10717706E@xxxxxxxxxxxxxxxxxxx> It's PART of the standard, which is better than nothing, and you can key on "List-Unsubscribe: <mailto:leave-researchbuzz" for determining if it's a list message or not. YahooGroups/EGroups/OneList uses this: Mailing-List: list printer-info@xxxxxxxxxxxxxxx; contact printer-info-owner@xxxxxxxxxxxxxxx List-Unsubscribe: <mailto:printer-info-unsubscribe@xxxxxxxxxxxxxxx> Delivered-To: mailing list printer-info@xxxxxxxxxxxxxxx The first two are standard, and the first one can easily be used to uniquely identify the list, as specified by the standard. Topica uses this: List-Help: <http://topica.com/lists/HeroTalk@xxxxxxxxxx/> List-Unsubscribe: <mailto:HeroTalk-unsubscribe@xxxxxxxxxx> BCentral, from MSN (aka Microsoft) has nothing, so, as usual, they are indeed conforming to standards but no one knows what they are. ListServ also has nothing explicit, but they have the excuse of being very old software, at least a decade old. This appears to be Mailman, not sure; that's the only name that I can find in common between an independent pair of lists that are otherwise identical. But, it comtains a nearly complete set of standard keywords: List-Help: <mailto:unattended-info-request@xxxxxxxxxxxxxxxxxxxxx?subject=help> List-Post: <mailto:unattended-info@xxxxxxxxxxxxxxxxxxxxx> List-Subscribe: <https://lists.sourceforge.net/lists/listinfo/unattended-info>, <mailto:unattended-info-request@xxxxxxxxxxxxxxxxxxxxx?subject=subscribe> List-Id: All things concerning http://unattended.sourceforge.net/ <unattended-info.lists.sourceforge.net> List-Unsubscribe: <https://lists.sourceforge.net/lists/listinfo/unattended-info>, <mailto:unattended-info-request@xxxxxxxxxxxxxxxxxxxxx?subject=unsubscribe> List-Archive: <http://sourceforge.net/mailarchive/forum.php?forum=unattended-info> This is from lists.abuse.net, no indication of what list software they're using: List-Help: <mailto:spamtools-request@xxxxxxxxxxxxxxx?subject=help> (List Instructions) List-Unsubscribe: (Use this command to get off the list) <mailto:spamtools-request@xxxxxxxxxxxxxxx?body=unsubscribe%20spamtools> List-Subscribe: (Use this command to join the list) <mailto:spamtools-request@xxxxxxxxxxxxxxx?body=subscribe%20spamtools> List-Post: <mailto:spamtools@xxxxxxxxxxxxxxx> List-Owner: <mailto:owner-spamtools@xxxxxxxxxxxxxxx> (Contact Person for Help) List-ID: <spamtools.abuse.net> --Scott. --Scott.
