Automatic mail sending

[eluser]Roy MJ[/eluser]
I did it in controller as eventually im planning to do mailing to emails selected from database. So first i was trying to get it working by static contents and static emails. I have found a Cron job application inside the cpanel in the advanced section. In that also we need to give a cron command. The command is what i had mentioned above. But its not working either. If you have done the mail sending, can you please tell me whats wrong with my code. I cant do it in simple php as it would mean i cant access the database.
