Hi and welcome to TSDN. Hope you have a great time here.
I'll move your question to the .NET forum.

My assumption is that admin@localhost is not a valid address.

thank u for ur reply
when i write as below
SmtpClient c = new SmtpClient("vcd 06005.vija.com" ,25);
c.Send(new MailMessage("ad min@vcd06005.vi ja.com", "admin@vcd06005 .vija.com", "sub", "body"));
i am getting that msgs are staying in c:\inetpub\mail root\drop without any errors

here
vcd06005 is my computer name
vija.com is my domain in local area network

but if write like below code i am getting error
SmtpClient c = new SmtpClient("loc alhost",25);
c.Send(new MailMessage("ad min@localhost", "admin@localhos t", "sub", "body"));

i hope u'll let me know the reason and solution

Localhost will not be equal to vcd06005.vija.c om. Its a term refers to ur system where iis is installed. By default it refers to the IP 127.0.0.1.

Try this, http://127.0.0.1:80 (80 is default port)

Clear now ?

RE me if not....

When it says "cannot relay" it is telling you that the user you have picked is not local to that server and your mail server is not routing email to them
(I find this happens when I don't authenticate with the smtp server)
