Can't use sendmail ( Program mode requires special privileges)

I just updated sendmail to the newest version and got into this trouble. Somehow only can root can use sendmail while the other users will simply get "SMTP went away" when using pine or

"can not chdir(/var/spool/mqueue/): Permission denied
Program mode requires special privileges, e.g., root or TrustedUser."

So I check the configure file and this is what I got

Is there anyway I can fix this?

What is the OS and version? What version of Sendmail (stating the 'latest version' may not be the version you are using)? What version of Sendmail were you using before the upgrade? (changes in Sendmail in the last few years may be the issue) Are you building/compiling Sendmail or is this downloaded "ready to use"?
