colinux dns fix

Emails from colinux were not coming to the radiosai.org address tho' the ones to the gmail address were being delivered. After checking spam and trash, checked out sending a mail from commandline and then checking /var/mail.info on colinux. Found that radiosai MX was not resolving, also mails to colinux root were bouncing saying that the file was too big. So, vi /etc/resolv.conf and added the opendns ips

nameserver 208.67.222.222
nameserver 208.67.220.220

Also did a rm * -f in /var/mail and restored the mailboxes with touch, chmod 600 and chown root:mail etc.
