debian-user traffic isn't reaching me

[Stefan O'Rear <stefanor@cox.net>]

The entire Page 5 in the archive hasn't gotten to my computer.
I stopped recieving Debian mail on the 13th.

I am using:
   fetchmail 6.2.5 (build from stock ESR tree, forgot to check debian
                    archives)
   exim 3.35-1
   mutt 1.3.28-2.2

I can send mail to my ISP account, and fetch/read it.
I can send main to my local address, and read it.
I can recieve spam.
I can recieve the Java Technology Newsletter.

When I send mail, I get messages like:

However, /var/spool/exim/db is owned by euid=8 (mail) egid=8 (mail), and
is owner writable.

What got messed up?
