e-mail to root

[jekillen]

Hello:
Is there a manual or other publication that deals specifically with
reading e-mail messages to root for FreeBSD?  I have gotten a
message:

setuid diffs:
--- /var/log/setuid.today       Sat Sep  8 03:01:34 2007
+++ /tmp/security.9Jz0CWds      Wed Dec 19 03:01:38 2007

followed by references to various programs

then the next segment:
Checking for a current audit database:

Downloading fresh database.
auditfile.tbz                                           46 kB   42 kBps
New database installed.
Database created: Wed Dec 19 14:40:00 PST 2007

Checking for packages with security vulnerabilities:

followed by numerous references to programs and
files on the FreeBSD site.

and I do not know quite what this means. I know that setuid is cause
for concern. I have three other machines with FreeBSD, with one
going back over a year of virtually continuous 24/7 operation and
this is the first time I have seen this type of message. For the 
programs
reported with security problems it begs the question of dependencies
if they are removed or updated. Some references are to cups and 
fetchmail
neither of which I use or have use for, that I am aware of. This 
particular
machine is primarily a web server. It does have Postfix running but just
uses local delivery and only listens on private network interface.
I am also a little dubious about posting any specifics to a public 
mailing
list.
I am admittedly a novice at this (on all my own systems so no one
else's behind is on the line). Short of paying consultation fees to
someone, this is about the only live contact I have on the subject.
Thanks in advance for info:
