hmm it means that  you have the group writable permission to the dir which shouldn't have .

Like in my example sendmail was running fine
-bash-2.05b# service sendmail status
sendmail (pid 1338 1329) is running...

"/ "permission ( note that its not group pr world writable)

-bash-2.05b# ls -ld /
drwxr-xr-x  19 root root 4096 Sep  2 06:00 /

-bash-2.05b# service sendmail restart
Shutting down sendmail:                                    [  OK  ]
Shutting down sm-client:                                   [  OK  ]
Starting sendmail:                                         [  OK  ]
Starting sm-client:                                        [  OK  ]


Now I have given the / as writable permission

-bash-2.05b# chmod g+w /

-bash-2.05b# ls -ld /
drwxrwxr-x  19 root root 4096 Sep  2 06:00 /


-bash-2.05b# service sendmail restart
Shutting down sendmail:                                    [  OK  ]
Shutting down sm-client:                                   [  OK  ]
Starting sendmail: 451 4.0.0 /etc/mail/sendmail.cf: line 98: fileclass: cannot o                                                                             pen '/etc/mail/local-host-names': Group writable directory
451 4.0.0 /etc/mail/sendmail.cf: line 578: fileclass: cannot open '/etc/mail/tru                                                                             sted-users': Group writable directory
                                                           [FAILED]
Starting sm-client: /etc/mail/submit.cf: line 528: fileclass: cannot open '/etc/                                                                             mail/trusted-users': Group writable directory
                                                           [FAILED]
-bash-2.05b#


So the summary is this that you should not  have group or world writeable permission to below dir or files. It should be like below:

-bash-2.05b# ls -ld /
drwxr-xr-x  19 root root 4096 Sep  2 06:00 /

-bash-2.05b# ls -ld /etc
drwxr-xr-x  69 root root 8192 Sep  2 06:00 /etc
-bash-2.05b# ls -ld /etc/mail
drwxr-xr-x  2 root root 4096 Jul 22  2004 /etc/mail
-bash-2.05b# ls -lrt /etc/mail
total 176
-rw-r--r--  1 root root  5588 Apr 15  2004 helpfile
-rw-r--r--  1 root root     0 Apr 15  2004 virtusertable
