Odd sendmail error

[Mark Knight]

One my 4.8 box I recently made a silly mistake sending a mail from the
command line, along the lines of:

   mkn at shrewd$ mail test at knigma.org -c test at knigma.org
   Subject: test
   test
   EOT
   mkn at shrewd$ WARNING: RunAsGid for MSP ignored, check group ids
   (egid=1001, want=25)
   can not chdir(/var/spool/clientmqueue/): Permission denied
   Program mode requires special privileges, e.g., root or TrustedUser.

Obviously I meant:

   mkn at shrewd$ mail -c test at knigma.org test at knigma.org

which works absolutely fine, so it's not a major problem.

I'd just be interested in knowing why my mistake lead to such an odd
message!  I believe my sendmail / clientmqueue permissions are the
installed default and sane.

Cheers,
