SUMMARY: Solaris 10 Sendmail problem

First of all, thanks to everyone and especially the following who each had 
a piece of the puzzle:

Andrew Watkins
Aaron Lineberger
Paul Sagneri
Crist Clark

The main problem was that I upgraded from Solaris 8 to Solaris 10 :)

Many of my problems surrounded the changes made to Sendmail in revision 
8.12 (Solaris 8 runs sendmail 8.11.7p3+Sun, Solaris 10 is at sendmail 
8.13.7+Sun). In sendmail 8.12 they introduced the default of not running 
suid root.

I had to remove the submit.cf file (which allowed mail to be recieved, but 
broke outgoing mail). I then modified paramenters in submit.cf to allow 
outgoing mail again.

I had to fix permissions on the various folders used by sendmail to update 
the proper users and groups for priv. separation (user/group smmsp, etc.)

I then had to clean up my sendmail.cf file to correct entries that were 
tolerated in the older version of sendmail, but not the newer.

Again, thank you to all who helped on this.
