Initial permission of /etc/mail/aliases.db

[Yasuhiro KIMURA]

Hello,

When you install any version of FreeBSD, initial permission of
/etc/mail/aliases.db is 640. But this file is generated from
/etc/mail/aliases and its permission is 644. So anyone who has account
can get all infomation included in /etc/mail/aliases.db from its
source file. Then is there any reason that permission of
/etc/mail/aliases.db is more restrictive than /etc/mail/aliases?

Best Regards.
