Correct me if I am wrong, but the right way to do this is to set the
hostname to just that - the hostname, and add 'domain foo.com'
to /etc/resolv.conf.  Then you should get something like (for say
www1.foo.com):

 $ hostname
www1
 $ dnsdomainname
foo.com
 $ hostname -f
www1.foo.com

I know for some buggy software the workaround was to set the hostname to
the FQDN, but that is really just a kludge, and the software should
rather be fixed (had to patch postfix some time back for instance).
