C# SMTP Send Email From Local Machine

Since I use my local machine for dev/testing, I currently testing the ability to send registration and other email communications to users. I'm setting my SMTP client to the smtp.domainname.com provided by discount asp.

I can create the SmtpClient with no problem as shown below:

mailClient = new SmtpClient(MapYourHike.Shared.Common.getConfigKey("SMTPServer"), 25);

However, when I attempt to send the email using the following code:

string expectionMsg = "";
try
{
mailClient.Send(message);
}
catch (SmtpException ex)
{
expectionMsg = "SmtpException has occured: " + ex.Message;
throw new ApplicationException(expectionMsg);
}

The following exception is thrown:

{"Mailbox unavailable. The server response was: <emailddress> No such user here"}

Do I need to set credentials to my mailbox in code?

What do you guys think?]

Thx for the input...

 

Try using 'localhost' as the smtp server. This is the web servers smtp service and it's the preferred method of sending out email with a web page. 'Localhost' will not require any smtp authentication to be passed by the application.

 

Thanks but I think I got it; I have to set the username & pwd for the account I'm using to send mail.

Tested it out and works great from my local machine

public Email()
{
mailClient = new SmtpClient();
mailClient.Host = MapYourHike.Shared.Common.getConfigKey("SMTPServer");
mailClient.Port = 587;
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = new NetworkCredential(MapYourHike.Shared.Common.getConfigKey("WebMasterAddress"), MapYourHike.Shared.Common.getConfigKey("WebMasterPassword"));
}
