From the Mail Delivery Reports, we notice that we average a handful of failures that reference the following message "SMTP error from remote mail server after RCPT TO:: 550-Verification failed for \n550-The mail server could not deliver mail to [email protected]". (For the interest in privacy, I have removed the actual name and domain name, but in all cases that address is the same.)
This email address uses the domain of the website hosted on this server. We do not have that subdomain set up and therefore obviously not that email address. What is confusing, is this error only occurs on some email transactions. Most are successful. Do we have to simply set up this subdomain and email address, or can this be remedied some other way? Any help would be appreciated.
