Unable to recieve mail from a specific ip

I am sending a mail through php to mail created by zoho mail from my website, unfortunately the mail is not recieved. The mail delivery track of my hosting provider states that the maii is sent to sales@mizzlecodes.com but it is delivered to mizzlecodes@mizzlecodes.com but such mail id does not exist and i have not used any redirection.
