Patch to run as "nullmail"

Hey guys,
Because the install script (make install-root) requires the user
"nullmail", I thought it might be convenient to have nullmailer-send
set its own uid at startup. I'm not using any daemonizing/supervising
tools to manage nullmailer. Could also make this a switch on the cmdl.
Are there any problems with this configuration?

Anyway, I love nullmailer and have removed sendmail from all my
servers. Much easier!
