Some email not sending
We have two domains - sslcnow and disabilitydatamanager (DDM). All sslcnow email is directed by Microsoft 365 (i think). I set up email accounts for DDM. From the webmail an email sent to [email protected] was bounced with this error:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
No Such User Here
but another email sent to a hotmail account went thru. sslcnow.com is the default domain in 365. We have no other issues with sslcnow email.
