Welcome, The Geeks !!
Lets start.. why often when we try to send emails through telnet goes in spam instead of inbox.. Ever wondered??
I am not expert, let me first tell you and please do correct me if i am wrong.
So after some research i found that when we sent emails through telnet.
The Received : path is our Public IP. which is the main reason i think how google differentiates an spoofed email and regular email. While when we send email normally through gmail accounts, the Received : path is different. you can view this in email headers..

Email header when email sent through telnet.. See the red underlined ( Its OUR public IP)
And email sent through normal Gmail account
And when sent through Sharmail.co.uk, if not seen my previous article then https://null-byte.wonderhowto.com/how-to/do-email-spoofing-using-sharpmail-0165272/
I hope i am correct.. And everyone got it how it works..
If so then can anyone tell me how can i change the
Received: from "myIP" to that of "mail-yk0-x236.google.com" as shown in 3rd image.
