email is blocked by SPF check

Hi, I have a program to send email. It is all right for recipents at yahoo and gmail. However, my email is blocked by the anti-spam policy of one of my client. As far as I know, they check the SPF to stop spam. My email is sent by VB program via an exchange server. The application server is on another machine. Can anyone tell me how I can capture my email server name in the header, which is my application server name at the moment. Or, I should set some kind of MX record to tell the other side to point to my email server. Thanks.
