Problem during domain verification

Problem during domain verification

Hi,

I’m having some issues while trying to verify the mijn-coffeebox.com domain. Everything’s set up but when trying to verify with an online tool the next email address:

admin@mijn-coffeebox.com

I’m having the next result:

MX record about min-coffeebox.net exists.
Connection succeeded to mx.zoho.com SMTP.
220 mx.zohomail.com SMTP Server ready January 14, 2016 12:57:00 AM PST

> HELO megacheaphosting.com
250 mx.zohomail.com Hello megacheaphosting.com (66.36.249.65 (66.36.249.65))

> MAIL FROM: <check@megacheaphosting.com>
=250 Sender <check@megacheaphosting.com> OK

> RCPT TO: <admin@min-coffeebox.net>
=553 Relaying disallowed

 

Could you please tell me what I’m doing wrong?
