Hi All: I hope this explanation will put to rest the questions about why, if you send a message to anyone on the list, you will get a message with the following: MAILER-DAEMON wrote: [log in to unmask] This merely means that [log in to unmask] did not receive the message for one of several reasons among which might be: 1) His mailbox on @macpro.ca is full. 2) His server is rejecting the message as he hasn't paid his bill but they haven't deleted his name from the server yet. 3) He has changed his email address and or his Internet Provider. 4) He is on vacation and the has not stopped the messages from his lists which ultimately overwhelm his mailbox. In any event, Murray did not stop his mail from the PIEN for his address, [log in to unmask], and his mailbox is overflowing. So every message sent to the list will cause Murray's [log in to unmask] server to reject the message and return it to the sender. Murray should have deleted his old address and instituted his new address in order to remain on the list, thereby preventing the overflow. This inaction is one of the reasons that undue overhead is created on the central processing systems with list functions. Another problem, even more severe is replying to a long missive and not deleting the total message before sending. This has a ripple effect since you send the old message material as well as the new, thereby creating a multiplier effect in data handling. If someone replies to the second message and doesn't delete any of the old information then we now are sending the content of 3 messages. AND we aren't sending it to a single person but over the entire list of 750 or more. When we talk about costs one can see how the multiplier effect takes place and we aren't aware of it.
