I have changed my .tk domain's name server to x10hosting's name server and added it as a packed domain,but I can't find where to set MX record in my cpanel.Is it impossible for free users to do so?By the way,I can't use phpinfo() on my site,it says phpinfo() is disabled for security.It seems I can't use cron jobs,either.What are other limitations for free users?Will I be able to use the PEAR package Mail in my php?
