Just to keep you informed on this thread, I got this from my postmaster today: The comment posted to the list that the name doesn't resolve is partially correct - there are no A records for dsl.pipex.com (since it is a domain and not a single machine). There are, however MX records which are used to determine where mail gets delivered to for that domain. An A record would only be needed if the MX record were not present. However, all this is irrelevant, as dial.pipex.com also has no A record and that works. I'll try prodding a few more addresses at Redhat to see if I can get any further with this. -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list
