Mail abuse. A great deal of spam and other mail abuse comes from computers on consumer feeds that are incorrectly configured as a mail relay (don't ask me how, but it happens more often then you would think), or have been compromised by some kind of malware and are being used as same. At the same time, SMTP was designed to move mail between static, well-connected systems. Hosts on dynamic, consumer feeds do not meet that definition. It makes more sense for such hosts to submit mail to a smart host which can do the job right. Of course, then you have to deal with the fact that a great many MUAs are incapable of doing anything themselves, and need to be able to submit mail to an SMTP-like listener. That is why the concept of an MSA (Mail Submission Agent) was created. The idea is to separate mail submission from mail exchange. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | _______________________________________________ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
