I don't use Telnet a lot so I will need the answer explained really clearly and simple. I want to connect to a website (gmail) with Telnet. I have looked at this post but I am too new to Telnet to understand it:
Send email from gmail using Telnet
So basically, I want to use gmail in Telnet. I don't know what code I need. I also don't know what to do before I start (I heard something about "enabling port 25"). So please just tell me exactly what code I can use (batch file) or what steps I should directly in CMD. Please post an answer as an answer and tell me if this question is better fit for SuperUser. I have looked at multiple StackOverflow answers to this but they were to confusing or not exactly what I wanted. I also found this link: https://technet.microsoft.com/en-us/library/bb123686(v=exchg.160).aspx and all was working fine with that method up until "MAIL FROM: sender@server.com" when I did that I got a syntax error. Why is that?
