17 april 1995 Ottawa One thing I need help with is addrressing mail to people on bitnet from my Internet site. Mail from the listserv obviously gets to them as it doesn't seem to come back and I know one of my subscribers was replying to mail which he was getting via the list. However when I tried to write to him as: [log in to unmask] or [log in to unmask] my mail system choked horribly here. I had not tried [log in to unmask] This is because mail coming in to me uses [log in to unmask]@uga.cc.uga.edu from some locations but it plain doesn't work for replies. Interesting the listserv docs say it sends mail and checks for accuracey and doesn't. I guess that is life. But it is not something a user should be able to do easily. If you read the between the lines of the RFC822 spec you will realize that any authenticity of sender and such is entirely the responsibility of the originating mail system and possibly of relaying mail systems but the spec does not require any authenticity verification as is obvious from the examples in th spec. This probably explains why some mail systems that allow editing of headers also ignore changes to certain headers and/or do not provide those headers for editing.
