Send Email though my program

sorry , i deleted this question.

Sorry, Boys for bouncing, early i deleted my question coz of some messed up.

so now i gave come with the correct question.

My proglram is like clip mark firefox plugin. But this is for the desktop.
so my users can capture the screen and mail to any one using the Microsoft CDO mail function. Now my problem is, i am on a shared hosting. So there might be email limitations.

So please advise me on how to handle this emailing though my program?
