I am facing the  same issue, I tried  using the EHLO command isntead of HELO and passing userId with AUTH LOGIN as suggested above. But now I get a 500 error when the DATA command is issued.

Hey Tareq,

Did it work for you? What other lib you had to download?

Hello ,

I am using the following code. It's actually the same that you've suggested. But it give an exception 

private static void SendAlert() {
            // Defines the sender
            SMTP_Client.MailContact from = new SMTP_Client.MailContact("brikesh987@gmx.com", "Brikesh Kumar");
            // Defines the receiver
            SMTP_Client.MailContact to = new SMTP_Client.MailContact("brikesh987@gmail.com", "Brikesh Kumar");
            var recipients = new SMTP_Client.MailContact[2];
            SMTP_Client.MailContact cc = new SMTP_Client.MailContact("brikesh987@gmail.com", "Brikesh Kumar");
            recipients[0] = to;
            recipients[1] = cc;
            // Defines the mail message
            SMTP_Client.MailMessage Message = new SMTP_Client.MailMessage("Small test result");
            Message.Body = "This mail is sent by a Netduino :-)\r\n";
            Message.Body += "Good day!";
            ushort port = 587;
            // Initializes the mail sender class
            try
            {
                SMTP_Client Sender = new SMTP_Client(new IntegratedSocket("mail.gmx.com", port), SMTP_Client.AuthenticationTypes.Login, "brikesh987@gmx.com", "****");
                // Sends the mail
                Sender.Send(Message, from, recipients);
            }
            catch (Exception ex) {
                Debug.Print(ex.StackTrace);
            }         
           
        }

I am also getting this error. Looks like this bug is not fixed. Did you guys find any other ways to send email?

Thanks for the response. Quite explanatory. Thanks again

Thanks for responding. I got the sensors, breadboard, connectors from radio shack. However I am still not able to find a netduino plus compatible wifi shield. Can you help me out?

Hello Friends,

I am fairly new to Netduino Plus platform. I bought one recently and have started playing around with it.

I am starting off a project which I need following :

1. A sound sensor compatible with Netduino Plus

2. A breadboard

3. A Wifi Shield

For Wifi shield, I saw Edimax been suggested on the forum (http://forums.netdui...56-wifi-shield/)

Can you please suggest me, for the above three, where can can I purchase them and which one to purchase. If it integrates with the Netduino board with minimum fuss.

Any help would be greatly appreciated.

Thanks,

Brikesh
