Wrong approach. While i admit that you still need some basic under-
standing of who's who in sendmail.cf, it's generally no longer recomm-
endable to tweak the sendmail.cf itself. Setup your .mc file instead:
cd /usr/src/usr.sbin/sendmail/cf
lpr -p README # that's the documentation
cd cf
vi myown.mc
make myown.cf
cp myown.cf /etc/sendmail.cf
(Perhaps we should provide /usr/src/usr.sbin/sendmail/cf even for
users who don't install the full source.)
UUCP feeds should be handled via the mailtertable feature. This is
how my uriah.mc file looks like:
include(`../m4/cf.m4')
VERSIONID(`$Id: uriah.mc,v 1.6 1995/02/23 18:14:53 j Exp j $')

MAILER(local)dnl

Cw uriah uriah.sax.de

...and this is uriah's /etc/mailertable:

bonnie.heep.sax.de uucp-dom:bonnie
.heep.sax.de esmtp:%1
pinky.UUCP uucp-dom:pinky
. uucp-dom:sax
Along with the README, this should give you a starting point.

Worse: yes. But not worst. I forgot the argumentation _why_ 1777 for
the mail spool is a security hole. Read the FreeBSD mailing list
archives on freefall if you're interested. I think, it's been
discussed about a year ago there. It's basically some sort of race
condition.
As long as you don't have a public access machine (and hence rather
``trusted users''), you probably don't need to care.
