Someone else mentioned the zero size. But a second thing to check is if
your users have the ability to read the directory itself. Even if the
file is readable, the directory must be rx (the "." and ".." are meant
literally):
cd /etc/mail/
ls -ald .
ls -ald ..

Should be owned and group root.
chmod 755 .
chmod 755 ..

If for any reason non-root is allowed write to /etc/, be very
suspicious.
