There is a good page that explains some of the security checks and why
Sendmail implements them.  By default, in most cases sendmail will not
trust group writable directories.  It considers it a security risk.

http://www.sendmail.org/~ca/email/doc8.9/op-sh-4.html

This page lists some tuning issues as well as how to turn off some of
those security checks.  I recommend evaluating what you are trying to
do, and make sure you are aware of the risks involved in changing the
permissions structure of sendmail.
