Does L-Soft have plans to add support for the use of the List-Id header described in RFC 2919 <http://www.ietf.org/rfc/rfc2919.txt>? If so, when? If not, why not? It provides a reliable method of identifying list messages. The 'To:' line is not reliable filter fodder. It usually contains the list address, but some subscriber option settings cause the recipient's address, rather than the list address, to appear on the 'To:' line. -- Paul Russell Senior Systems Administrator OIT Messaging Services Team University of Notre Dame
