	Sounds to me like smap or sendmail needs to be SUID root (to bind to
	the low numbered smtp port (25)).  If this happens even when you
	are root, it might be that sendmail is owned by the wrong user/group.

	Sound like more ownership/permission problems -- does FreeBSD
	need to be SGID kmem (or something like that).

	/dev/ entries aren't regular files -- they are devices (specifically
	they are links to devices which allow Unix to treat devices as 
	"files" for purposes of programming abstraction).  The sizes reported
	are not "additive" to the file sizes reported by other files.

	specifically these are the "raw" nodes (links).  There should be 
	corresponding "cooked" links named /dev/sd*

	If you want to actually find the amount of filesystem space consumed
	by a set of files use the 'du' command (disk usage report). 
	If you want to know how much space is available on your filesystems
	use the 'df' command (disk free report).  For the most part my advice
	is to leave the "files" in the /dev and /proc directory trees
	*alone* until you know much more about them (I leave them alone
	in any event).  

		*VERY BAD THINGS HAPPEN* if you remove or modify these "files."

	It sounds like you did something after the basic install.  The 
	FreeBSD 2.1 installations scripts (from the CD at least) would have
	set all the permissions and file ownership correctly.

	I'd recommend that you re-install from scratch.  You could probably
	find and surgically fix the couple of problems that you described --
	but I'd be really worried of what else was broken (particularly since
	some of the values of "broken" lead to nasty security problems).
