Out of interest I just copied the program to my work system (also
Fedora 7, but a different network environment of course) and there the
program produces:-
hostname = 'chrisg.atroad.com'
canonical = 'chrisg.atroad.com'
alias: 'chrisg'
.... and on this work system mail to chris@xxxxxxxxxxxxxxxxx *does*
get delivered to me, I'll investigate!
