Hi Tomoyuki,
Yikes! I don't see a simple way to make full headers (or even better, the full raw email) available in an automatic fashion. Perhaps you can directly subscribe to fukuzawa (or subscribe fukuzawa to some free email account)? While I can see some usefulness of full headers in terms of reporting abuse (including spam), I don't plan to add it to the service. Additionally, the host name www.mail-archive.com is what I generally refer to for the list archive service - while marmot.jab.org is (currently) another name for the same machine, I don't recommend disseminating it widely - it could change next time I mess with hardware. Cheers, Jeff
