smtp??

Hi,
I am using a simple Mail application. I am using a smtp server to mail the
mails. But the problem here is the hackers are sending spam mails from the
same smtp server as this is the live open smtp.
Is their any option to secure your smtp server. I mean can we give any
username / password to the smtp server settings. If yes just give me the way
out.
