At one time it was considered highly suspicious to want to send
mail with something other than your username and host in the
>From line.  Old timeshare-based email programs did not provide
a way to do it.

Obviously things change.  But it's not totally evil to want to do
it the old way.  It's faster and simpler to determine what account
was used to send problem mail.  I can see that side of it.
