Hi,
the smtpd(8) daemon supports "deliver to maildir" out of the box,
and even though putting the user maildirs below /var/mail/ is not
the default, it's one of many possible and logical choices, and i
see nothing wrong with it.
Adam Wolk noticed on misc@ that currently security(8) doesn't
like that choice. I consider the complaint gratuitious and the
code to prevent it simple enough that i'd like to commit it.
Any OKs?
Ingo
