Bouncing SMTP. Failure policy error,

Bouncing SMTP. Failure policy error,

Hi.

I just received a strange message from a mailing server that says that number of messages are getting bounced by  zoho mail server.

Reason follows :

------------------
Action: failed
Status: 5.1.1
Remote-MTA: dns; mx.zoho.com
Diagnostic-Code: smtp; 552 5.1.1 < david.marec@davenulle.org> Mailbox delivery failure policy error
-------------------

What is this policy that rejected  incoming messages ?

That is to say, there are number of messages that were dropped without notification ?



Bounce sample :
