ASP.NET problem sending emails with custom to address

[stevell]

hi,

I'm in the process of creating my own ASP.NET mailing list. I'm using the following code to send emails:

public static void Send(string to, string from, string subject, string message)
{
MailMessage email = new MailMessage(to, from, subject, message);
email.IsBodyHtml = true;

(new SmtpClient()).Send(email);
}

The problem is is that an exception gets thrown if I send an email to an address that hasn't already been setup in the eukhost control panel. PLEASE don't tell me that I will have to individually create a different account per recepitent in the database?!

I'm assuming I have in someway not configured the above code correctly?

Hello Stevell,

Can you make sure that the SMTP server name you are using is localhost . Also if you still face problem please provide us with the exact URL which throws execption .

Can you tell me why that would help? I'm assuming its so that you can see the execption?

I have some more details after trying configuring it with localhost.

The code used to send the email:

MailMessage email = new MailMessage(to, from, subject, message);
email.IsBodyHtml = true;
SmtpClient cl = new SmtpClient();
cl.Host = "localhost";
cl.Send(email);

Also I have some other configuration in my web.config i found:

<system.net>
<mailSettings>
<smtp>
<network host="localhost" password='****' userName='*******' />
</smtp>
</mailSettings>
</system.net>

And lastly here is the ASP.NET exception I get:

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Net.Mail.SmtpException: User not local; please try a different path. The server response was: Sender address is not valid for your login.

"localhost" would have helped as the server is sure that the domain that is using the mail server is a local address.

For the error that you receive, I would suggest you to make sure that the From: email address used in the script to send email is a valid and local email address. Also you will not be able to send emails if you authenticate with the email 'info@domain_name' and specify From: address as 'sales@another_domain'.

Just to re-clarify my original question. I already know how to (and can) send emails using a registered local email address in the to and from fields. However in the process of creating a mailing list I want to use a local from address and a non local to address. That is where the problem lies.

So, is it not possible? Or is there some different smtp configuration I need to use?

Yes, this is very much possible. I would suggest you to set the email server as localhost with no authentication. And you if you still face any problem then please email us on windows [at] eukhost.com with the link where you get the errors and we will have a look at the email script.
