For the past 24 hours I have been receiving the following message (about 1 per 30 seconds):
Your message cannot be delivered to the following recipients:
“Recipient address: commissionexpress@CEFA
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;554 5.7.1 <commissionexpress@CEFA>: Recipient address rejected: 550 Message rejected; not accepting mail for this address (H602)
Remote system: dns;dc01m01.norada.com (TCP|17.148.16.103|60261|209.205.33.195|25) (dc01m01.norada.com NO UCE ESMTP)“
This was the dropbox address I created. I now have thousands of FAILURE-DAIMON notices. How do I stop this and why is it occuring?
