That sounds like a problem with the server you're sending mail to.

Your server works fine apparently.

You can check if your IP is blacklisted here: http://mxtoolbox.com/blacklists.aspx.
The domain is not black listed. I am not even able to send to hotmail or outlook.
Only for gmail and yahoo its working and for other domains 550-No Such User Here 550 Sender verify failed error is displayed.
What's your domain name?
can you please help me on this as I have searched everywhere but nothing is working..
Odd, I've never seen that happen before. How are you trying to send mail?
I tried with both php mail function as well as from round cube. same errors.
I even created a fresh droplet but same problem happens there as well.
