From: Matt Kraai <kraai@asturias.ftbfs.org>
/etc/mailname contains the hostname to be used on outgoing email messages generated locally on Debian systems (cf. http://www.debian.org/doc/debian-policy/ch-customized-programs.html). If it available, use it instead of gethostname or gethostbyname.

If this is only appropriate for the Debian package, I apologize. Please let me know if this is the case and I'll submit it to the Debian maintainer.
