sendmail config problems

Dear Tru64 experts

I decided (in retrospect rather unwisely) to upgrade sendmail from 
8.11.1 to 8.14.3 on my old DS20, running the final version of Tru64 
5.0 with all the patch kits.

I chose the file generic-osf1.mc as the sendmail.mc file during the 
build.  There were no errors in the build output.  However, now when 
I try to send mail:

# mail [email protected] < /var/adm/syslog.dated/current/lpr.log
can not chdir(/var/spool/clientmqueue/): Permission denied
Program mode requires special privileges, e.g., root or TrustedUser.

The above is executed as root!  When I look at the directory that it 
says it cannot open:

# ls -lt /var/spool | grep queue
drwxrwx---   2 smmsp    smmsp       8192 Aug 19 08:30 clientmqueue
drwxr-xr-x   2 root     system      8192 Aug 18 12:43 mqueue

mqueue of course was the queue for the old version of sendmail; 
clientmqueue was created during the new build.

Do I need to do anything to the permissions (eg. like put root in the 
new smmsp group, probably a bad idea) or is there something I needed 
to tweak in the sendmail.mc file before building?

Any suggestions gratefully appreciated.
Cheers
Derek
