Formerly when I received mail for lists to which others at YALEVM also subscribed, the mail arrived with all of us listed in the To: field and apparently only one copy of the mail was sent (or distributed ?) to MAILER@YALEVM for delivery to local subscribers. Now each of the YALEVM subscribers receives an individually addressed copy; that contributes unnecessarily (and significantantly, I presume) to the increase in network file traffic! It also unnecessarily hides from local subscribers the answers to the questions: "Who has already seen this mailing?" or "Who else is interested in this topic?". What happened to "multiple addresses in a single copy" distribution over the network? What caused this change to less efficient delivery? Is there some reason why we can't resume distributing one multiply-addressed copy of each list mailing for all addressees served by the same MAILER ?? Jim Owen (YCC postmaster)
