Failure sending mail

[pb2000]

Hello,

Example is simple, shown on many forums, but not working.

        MailMessage mail = new MailMessage();
        mail.To.Add("add1@gmail.com");
        mail.From = new MailAddress("add2@gmail.com");
        mail.Subject = "Test Email";
        mail.Body = "Hello";
        SmtpClient smtp = new SmtpClient();
        smtp.Host = "localhost";
        smtp.Send(mail);

On last line I obtain exception: "Failure sending mail".

Anyway, Is it possible to send mail from my workstation (localhost)?
If yes, then next problem occur - Mail.From Address. Shoud I provide sender address when I send from localhost?

I tried examples from many sources. Unfortunatelly, results the same..

Thank You for Your help.

Sure... if your local workstation happens to be running an SMTP server.

Since it probably isn't, you'll need to log onto your mail server using the same credentials your account in Outlook uses.

Hi,

First - You can send from "localhost" only if you have a smtp server installed on you station. (like FreeSMTP http://www.softstack.com/freesmtp.html).

Second - In case you are using a remote SMTP server, lets say your ISP server.
the "From" field is not always customizable.

Some server are checking this field so the only "From" address is yours.
from ex':
if you are trying to connect to EarthLink server @ smtp.EarthLink. com
and your user is "abc" then the only From address you can send from is:
abc@earthlink.c om.

this validation is usually been applied in mail server to prevent a fake sender.

Hope this one help.
