For example: a domain owner send an email like this: a@yahoo.com to google.com and set in it's DNS server that when google check the IP address of domain manually that this is yahoo.com IP not the domain IP and when google check the IP of sender google doesn't know that this mail is from domain not yahoo. so please guide me is it possible or not? and reason of the answers.

Yes yes and yes. You can do anything on the internet. Sadly enough spam filters and the antimalware programs are smart enough to catch these tricks. I remember previously C# Corner sent emails using the user's address as the from field and my gmail would show that this is not from this account. So the answer is yes the spam filters will always know and in most of the cases they will not even send the email that you are intending to deliver to your clients. Another thing to keep in mind is that when you are sending the email from let us say a@yahoo.com and you are sending it from Yahoo SMTP server you need to login to that account and in which case the email account is yours . If you are going to use this account and send the email from Google SMTP then maybe they block your email and ultimately your account if you keep doing that. Can you share the business interest that you are having so that we can guide further if possible? Otherwise this will just get you banned from Google's SMTP services. Don't do it.

No that would just be a waste of time.

So you mean It is impossible to underestimate google security protocols to do this action?

Afzaal Ahmad Zeeshan · Answer

They do not use the SMTP servers set up by Google or Yahoo etc. They create their own servers using Linux servers where you can write the minimal programs that run and do the task. What hackers do is they just send the data from their own build minimal SMTP servers using the native TCP protocol. Do not forget their emails are also checked scanned and blocked in most of the cases. You can do the same build your own SMTP Server then send the email from your own server using the account (any account) and if the recipient's email box is not guarded your email will be delivered. Note that it is also possible from your own accounts but the security is really high and thus it won't happen .
