system.net.mail question

Hi

I am using system.net.mail to generate an E-mail from my form. When I recieve the message the header shows

MIME Version:1.0MIME Type:text/plain; charset=us-ascii

I am trying to determine if the MIME is getting added from the source server that is sending our email or the server where we retrieve our email from. Or can this be controled by system.net.mail? Any help is appreciated.
