Hello, I tried to send an email invoice just now and the following message came back
Mailbox unavailable. The server response was: 5.7.1 rejected as Spam 2 4153
I then tried to send the email to myself and it has came back undeliverable
I tested the email settings and the test message was successfully sent
I searched the forum with a cut and paste of the information, but there was no current topic.
I checked with Microsoft and could only find information on spam due to filtering
