eprint error email

[RCP45]

When I attempt to print with HP eprint I get an error message via return email. It takes a whole day to get the return email.

In the following the "XXXXXXXXX" is actually the email address shown by my printer and by the printer's EWS page printout.

This is a delivery failure notification message indicating that
an email you addressed to email address :
-- XXXXXXXXX@hpeprint.com

could not be delivered. The problem appears to be :
-- Recipient email address is possibly incorrect

Additional information follows :
-- 5.7.1 <XXXXXXXXX@hpeprint.com>: Relay access denied

This condition occurred after 1 attempt(s) to deliver over
a period of 0 hour(s).

If you sent the email to multiple recipients, you will receive one
of these messages for each one which failed delivery, otherwise
they have been sent.

Welcome to the HP support community.

Did you make any changes to the ePrint account?

When did this issue start?

how do I stop Mimecast from blocking my eprint jobs?  

[RCP45]

I am just going to ignore this as I don't really need that feature anyway.

WHAT IS THE SOLUTION FOR GOODNESS  SAKE? I AM SO MIFFED BY THIS NONESENCE

[RCP45]

Just because I decided to ignore the problem does not mean the problem was solved.

You don’t actually give the solution to this blasted problem. Mimecast. Mimecast. Mimecast. 
how and why did you do this. My print page says Hp Mimecast. So it must be yours. 
what on earth is the solution?

I am really peeved at this nonsense.

Welcome to the HP support community.

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).

If you are unfamiliar with how the Community's private message capability works, you can learn about that here.

Thank you for visiting the HP Support Community.

Our printer will periodically reject emails as well, with his same NDR. How can we permanently whitelist our sending email account.
