Hi,
I am using asp.net 3.5 version and trying to send email from my application. I am using following codes:

C#

MailMessage Mail = new MailMessage();
Mail.From = new System.Net.Mail.MailAddress("username");
Mail.To.Add("recipient mail id");
Mail.Subject = TextBox3.Text;
Mail.Body = TextBox4.Text;
Mail.Priority = MailPriority.High;

SmtpClient smtp = new SmtpClient("smtp.gmail.com");
smtp.Credentials = new System.Net.NetworkCredential("username", "password");
smtp.EnableSsl = true;
smtp.Send(Mail);

But I am getting following error:
The requested address is not valid in its context 74.125.47.109:25

Can anyone send me the proper code to resolve this error.

Is the port open? Firewall permissions in place?
Further make sure you have configured SMTP configuration in Web.Config:

<system.net>
   <mailSettings>
     <smtp from="abc@somedomain.com">
       <network host="somesmtpserver" port="25" userName="name" password="pass" defaultCredentials="true" />
     </smtp>
   </mailSettings>
</system.net>

If needed, have a look at this Microsoft Video tutorial:

If needed, there are lots of article on this very site on how to send emails.
