Just think of it as a digest, but the digest is sent out every time a message

I guess it's unlike LISTSERV in that respect, which is able to filter
autoresponders and send them off to owner of the list. Also, if the message
came from the mailing list install of the original person, then a person could
configure their vacation program to ignore messages from that address.
