How to sent on behalf of mail in C#.NET

In this post I am want to tell how send behalf mail in C#.NET. Behalf of mail is means, it is like normal mail send only. But we will add Sender option in that mail header. So, I second side when they’re view that mail in from mail ID option they can see like this [sender mail ID] on behalf of [from mail ID].

We can send behalf of mail in C#.NET easily, same like VB.NET too. Please check with image how it will be in receiver side.. if you see this mail you can understand what is behalf of mail?..
