2002-07-15  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-mime-utils.c (header_msgid_generate): Try to get the FQDN
	from the results of gethostname(). If that fails, then fall back
	to the results gotten from gethostname() or if that fails just use
	"localhost.localdomain". Addresses bug #17416.
	(header_decode_param): Protect against a NULL value.
