Here are the most common causes for blocked messages in the Delivery
Manager graphs, and the steps to resolve them:
• Delivery Errors
Your server may be returning errors when the message security service tries
to deliver mail.
Run SMTP Message Test “Test an email from the data center directly to your
mail host”. See SMTP Message Test.
If you see problems, contact your mail server vendor or administrator to
resolve these problems.
• Incorrect Delivery Information
The message security service may be trying to deliver to the wrong location.
If this is the case, update your Delivery Manager settings. See Setting up
Delivery Manager.

are being spooled. (You can also click the Spool Mgr link near the top of the page
to find out if spooling is happening.)
