Hi Imar,

I keep getting the following error when doing the example on pages 319 and 320

Server Error in '/Site' Application.

The code is exactly like in the book. Can you take a look and help me out.
SmtpClient mySmtpClient = new SmtpClient();
mySmtpClient.Send(myMessage);

Thanks.

Hi there,

Have you tried specifying a username / password, ssl and/or port number in the web.config? Who's the administrator of the SMTP server on this IP address? Maybe they can provide you with the correct setup details?

I added this to the web.config file

Code:

 
<system.net>
        <mailSettings>
            <smtp deliveryMethod="Network"
                  from ="xxx xxx &lt; [email protected]&gt;">
                <network enableSsl="false" userName="[email protected]" port="25" password="xxxx" host="smtp.sercureserver.net"/>

            </smtp>
        </mailSettings>

I use GoDaddy for my hosting and email.

Imar · July 14th, 2011, 12:59 PM

Maybe GoDaddy doesn't allow you to connect to a different server, or the server doesn't use port 25? Doesn't GoDaddy provide you with a SMTP server?

I switched the settings to use gmail and i still get the error message.

Code:

 <system.net>
        <mailSettings>
            <smtp deliveryMethod="Network"
                  from ="name &lt;[email protected]&gt;">
                <network enableSsl="true" host ="smtp.gmail.com" port="467" password="password" userName ="[email protected]"   />

            </smtp>
        </mailSettings>
    </system.net>

The error keeps pointing to this

Code:

 MailMessage myMessage = new MailMessage();
        myMessage.Subject = "Test Message";
        myMessage.Body = "Hello world, from Planet Wrox";
        myMessage.From = new MailAddress("[email protected]", "name");
        myMessage.To.Add(new MailAddress([email protected]", "Receiver Name"));

        SmtpClient mySmtpClient = new SmtpClient();
        mySmtpClient.Send(myMessage);

Thanks

I think Gmail uses port 587. Take a look here: http://imar.spaanjaars.com/505/using...at-require-ssl for sample code that works with Gmail.

Hope this helps,

Imar

Hi Imar,

I used the sample you provided for gmail setup in web.config. I keep getting this message.
Please note that when i have it send to a temp folder on my desktop it works fine. Can you please take a look. Thanks.

Can you show your web.config file? It works for me with the code from my article so if you use the same settings, your network may be blocking the connection.

Cheers,

Imar

Here is the web.config code:

Thanks

Code:

<configuration>
  <appSettings>
    <add key="MyEmailAddr" value="[email protected]"/>
    <add key="ToEmailAddr" value="[email protected]"/>
    <add key="EmailHost" value="smtp.gmail.com"/>
    <add key="FromEmailAddr" value="[email protected]"/>
  </appSettings>
  <system.net>
       <mailSettings>
           <smtp deliveryMethod="Network" from="[email protected]">
               <network enableSsl="true"
                 port="587"
                 userName="[email protected]"
                 password="xxx"
                 host="smtp.gmail.com"/>
               
           </smtp>

        </mailSettings>
        
  <!--  <mailSettings>
      <smtp deliveryMethod="SpecifiedPickupDirectory">
        <specifiedPickupDirectory pickupDirectoryLocation="c:\Documents and Settings\xxx\Desktop\mail"/>
      </smtp>
    </mailSettings> -->
  </system.net>

Then I think it's an issue in your local network such as a firewall blocking access to port 587.

I copied and pasted your config code and then send a message using it. Works fine for me.

Cheers,

Imar
