Hi, it's been a while since I took a look at this topic. While playing with telnet on my mail server, I noticed I only get responses from the mail server when I send the Helo, mail from and rcpt to commands. The only other response comes after the message is sent, which said something like "Message scheduled for delivery."The added code works fine under emulation and shows the SMTP server responses, however running it on the Netduino Plus, the SOCKET.POLL times out , suggesting that the SMTP server is not sending anything.
Am I missing something here?
Do you happen to be running the function in between the other commands?
