Description redneb 2013-08-09 14:15:50 UTC

The file /etc/nullmailer/remotes contains plaintext passwords to remote smtp severs. I think it would be a good idea to install it with more restrictive permissions. I tried with root:nullmail / 0640 and it seems that everything works without any issues. The ebuild for mail-mta/ssmtp does a similar thing for its equivalent file. Here's the relevant snippet from that ebuild:

	if ! use prefix; then
		fowners root:ssmtp /etc/ssmtp/ssmtp.conf
		fperms 640 /etc/ssmtp/ssmtp.conf
	fi
