554 5.2.3 MailPolicy violation Error

Good morning,
I have a problem receiving some mails. When I try to send an email, the external account receive an automatic message: 

554 5.2.3 MailPolicy violation Error delivering to mailboxes


Final-Recipient: rfc822; andrealopez@auguri.com.co
Action: failed
Status: 5.2.3
Remote-MTA: dns; mx.zoho.com(216.52.72.121, the server for the domain auguri.com.co.)
Diagnostic-Code: smtp; 554 5.2.3 MailPolicy violation Error delivering to mailboxes
Last-Attempt-Date: Wed, 07 Jun 2017 07:38:11 -0700 (PDT)

Is it problem related with size capacity of the mail? What can I do to solve this, becasuse I need receive mails with attachments about more than 10MB.


Thank you very much,
Andrea López
