Ben, My guess is that something is getting prepended to ".byu.edu" as your entire hostname, and that name does not resolve. Many DHCP environments do give you a hostname, whether you realize it or not.
Since your environment is dynamic, you should probably consider always sending mail through the lo interface. Try this kind of set up: 1. edit your hostfile so that my.laptop points to 127.0.0.1. Yes, the domain is bogus. 2. open up main.cf and set myhostname = my.laptop 3. set mydomain = laptop 4. make sure mydestination includes $myhostnamne, localhost.$mydomain, $mydomain (that should be default). In your mail client, set your smtp to my.laptop. One catch is that anything mailed out from a user that does not specify "@somedomain.com" will appear to come from [EMAIL PROTECTED] Also, having never tried this myself, I don't know other gateways will act when they see the non-resolving hostname. But hey, it's worth a try. Gary On Thu, 09 Sep 2004 12:46:42 -0600, Ben Crowder <[EMAIL PROTECTED]> wrote: > I've tried to figure this out for several days now but it's just not > working.
