I currently don't have this define and I would think it
is running as 'daemon' as that owner of files sendmail
will create ..

I've seen this mentioned as Sendmail.conf as well .. and
why in the lib dir?  WHen built from pkgsrc it is installed
in /usr/pkg  .. 

With the sasldb is an AuthFile even necessary in /etc/mail ?
