Please be more verbose.
Why should gethostname() not return the valid hostname of the host
it runs on?
If it doesn't return something useful, I'd expect /etc/hostname and
thus the hostname setting to be bogus and correction-requiring.
On Debian installations, the name in /etc/hostname and /etc/mailname and
/etc/hosts should be consistent. If this isn't the case, the local
admin has botched it, I'd say until proven otherwise.
