The command which GDS uses to generate "From: Gregbo" is a power
tool in MM and not a result of any failure in it.  There are
other commands which can be used to "become" some other user which
do ensure valid RFC 822 header lines.  A "power tool" is something
which lets the user go beyond the program's (narrow) interpretation
of whatever standard...either to use some unimplemented or new
feature...or in this case to violate it.

Just like somebody can hurt themselves with a chain saw, one can
abuse a mailsystem power tool.  But blame the user, not the tool.
