You need to check the sendmail.cf and submit.cf files to see what user
the programs are trying to run as. Generally, sendmail tries to run as
root when it's doing things such as creating mail queue entries and as
user 8:12 (mail:mail) when doing other things such as delivery and
such. smclient usually runs as user "smmsp" at all times.
As far as /var/run/sm-client.pid, the trick is that it is created by
root's performing a "touch" of it first, then does a "chown smmsp:smmsp"
of the file BEFORE sm-client is fired up. Check
/etc/rc.d/init.d/sendmail for details.

That's rather odd. Your command line doesn't specify a "-r" anywhere.
This leads one to believe that one of the programs (possibly "tr") got
whapped and is spewing out garbage. You really should try redirecting
the output of it to a file to test it:
cat $FNM|tr 'A-Z' 'a-z' >/tmp/testoutput
and you should look at the expansion of "$ACCESS" to see if it has an
embedded quote or something in it.

Lightweight! I've been running on 3 hours of sleep or less per night
for 3 weeks. If you're looking for sympathy, you've come to the WRONG
place! :-p
