My knowledge level in network >transmission is quite low. Because those headers that contain generic addressing do NOT require extra e-mails to be delivered and can be sent with multiple RFC821 headers, but only one imbedded "To:" (RFC822) header) i.e., all recipients of the distribution at a particular site receive the same "To: " field and thus LISTSERV is able to take advantage of that by only transmitting a single copy over the net. "Personalized" To: (RFC822) require a separate and distinct e-mail transmitted for each individual receiving same. There are circumstances where the latter IS required (in my experience). -- co-owner INFOSYS, TQM-L, CPARK-L, ERAPPA-L, JANITORS, LDBASE-L, et -L [log in to unmask] "No joyriders on the Info Super Hiway!"+1 814 863 1843 31 Shields Bldg. -- Penn State Univ -- University Park, PA 16802-1202 USA
