Most? How many list members, for example, have their own email server
rather
than rely on some ISP's mail server even if not their primary one? A mail
server has to talk to at least one other mail server and the whole chain
relies upon limiting the amount of information sent. A mail server is not
expected to talk to every potential end user mail server to send one or
more
messages.

But it makes little difference, since the original propogation remains one
message, and as it is relayed around and distributed it grows into more
messages. Yahoo for example will send one message to their email server
which will then relay a small number of messages to other servers for
further propogation. A quick look at the headers suggests list messages go
through a number of yahoo servers before heading out onto the net so they
will definitely not be doing it as message per user per list. I doubt even
Yahoo cannot afford multiple Microsoft style bandwidth funded by a widely
failed ad revenue system :)

Rarely does a message go direct from your (or ISP) email server to a
destination email server since to do so would introduce unecessary lag in
the chain. Redundancy and all that :)
