Camaleon, Thanks for your patience, and I seem to have stumbled on my problem: emim4 configuration.
Regarding the value for "system mail name", in retrospect it does makes sense, but not when I was reading the document you cited. First, if I can reconstruct my thinking correctly, I failed to associate the word "mailname," which was not explicitly defined, with "domain". If I asked someone on the street what their "mailname" is, they would give me their email address. I knew that it actually meant domain, but I had to figure out from its function that it was not really the "system" name (i.e., the domain of a host on a LAN), but the alternative meaning of domain, which unfortunately has no dedicated term such as "internet domain". I may be dense and my reading perverse, but it's folks like me that manuals are for ;-) In any case, the source of my problem was my adding my domain name to the list of recipient domains. Again, in retrospect, I understand why this caused exim4 to fail to route a message to another machine that happened to have the same domain name before the LAN was set up. Exim4 naturally looks for the user's of that domain name on its own host or local network and, not finding the user, does not by default ultimately send the message to my provider's mail server. Instead, it simply gives up and returns a routing error message. I guess the assumption is that if a person assigns a local domain name to the host, they intend to make it part of a LAN, and so instinctively know that until such a LAN is actually in place, the local host is not able to send a message to another host having the same domain name. My problem was that I tried to set up and test email before constructing the LAN. Haines -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
