Mail security

[Steven M. Kramer]

I was going to stay out of this argument, but now I can't resist.
The 'readability' of a mail file is a compromise of security (if
such things are security-relevant things on your system).  
The ability of someone to rm the mail file is not a loss of security
but rather a loss of data integrity.
	To fix the security problem -- make MAILMODE ~600.
	To fix the integrity problem, make the mail dir 755 (root)
	and define the thing that doesn't remove mail when all read
	(because ucbmail is not setuid).
