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).
