1) in /etc/mail/sendmail.mc, change the following:
	define(`confSAFE_FILE_ENV',             `/')dnl
   to
	dnl define(`confSAFE_FILE_ENV',             `/')dnl

2) the default uid/gid for delivery agents is 1:1 (daemon), if you want
   to write arbitrary files, you can either chown them to daemon:daemon,
   or, put the following in sendmail.mc:
	confDEF_USER_ID     DefaultUser [1:1] Default user id.

*NOTE* *NOTE* If you change the default user to root - you're going to
allow *ANYONE* *ANYWHERE* to write *ARBITRARY* files on your system !!!
