Problem in Email Project.

Question

Dear All,
I have written a windows based program to send an email to any client. It is ok. But what should I do when there is no registered SMTP server with me. Can any body give me any solution?
Although I got few of free SMTP servers from internet, but after installation, they are unable to work.

II)
How do I create the inbox program?
How to retrive header information of received mail? say; To, From, Subject etc

I am using MS .Net 2003 with Sql Server2000.

Thanks in advance.
