Impact on Non-Root Users
With the change in permission, non-root users cannot access the files and databases
associated with Sendmail, and a Permission denied message appears when you
run any utility that access the Sendmail files and databases.
The following messages appear when you run the praliases and mailstats utilities:
$ praliases
praliases: /etc/mail/aliases: open: Permission denied
$ mailstats
mailstats: /etc/mail/sendmail.st: Permission denied
