I did a delete of the thread and then thought that perhaps the data should be expanded.
But, note that the comments including Daniel's were right on. Explaining how mail delivery works to non-experts is not easy. It involves explaining address resolution both within NT domains and in the DNS world. It also involves explaining the role of relay hosts and any address rewriting that is going on. For most people, words are not going to cut it. Years ago our Exchange team faced the same problem and developed a system of very simple charts that show a check list of each system or handshake that has to occur, and then a separate chart explaining exactly how each one works, packet by packet. They called these happy charts. Now admittedly, even these are not telling the truth, in that the role of caches in the switches and routers is left out, and it is assumed that things like DNS resolution actually hit the DNS servers every time, but that's a level of complexity (or honesty) that is not really necessary to get your points across. I think you would do well to draw your happy charts. They will make explaining the shorthand a lot easier. My hesitation in mentioning this stems from the fact that it is in the archives maybe a dozen times, but periodic repetition is not a bad thing I guess. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
