5.4.1 Mail rejected by destination domain

Hi,

I was testing contact form on my website and looks like my server now in your spam list.

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

hello@3rdfloortailors.com
host mx.zoho.com [165.254.167.50]
SMTP error from remote mail server after RCPT TO:< hello@3rdfloortailors.com >:
541 5.4.1 Mail rejected by destination domain

Please, modify the spam filters to accept emails to from my website. Thank you
