SMTP Error (550) (New Setup)

I am trying to setup the emails and followed the tutorials.
Also searched here only one question come up and that too I already did that.

I am not able to send emails except own domain, hotmail & gmail.
If I am trying to send it then getting this message.

SMTP Error (550): Failed to add recipient “” (No such recipient here).

Anyone can give me a hand!
Kind regards

Hi, I’m also facing the same problem. Did you have any solution for this?

Hi Gideon
I just waited for DNS to fully propagation and then it solved. Also, I learned you cannot email your self.

Hello Munish,

Thanks for your reply. Yes, the problem is because MX record has records of Google and MXRoute. After I deleted Google’s, it’s working now.
