62 Message Security Troubleshooting Guide
The graph will look like this:
Here are the most common causes for problems with mail flow when you see
accepted messages in the Delivery Manager graphs, and the steps to resolve
them:
• Internal Routing
Your mail gateway (or mail server) may be accepting messages initially, then
losing messages during internal routing.
Send a test to see what happens when mail is sent directly to your mail
server. Run an SMTP Message Test with the “Test an email from the data
center directly to your mail host” to find out what might be happening. See
SMTP Message Test.
After this, troubleshoot your mail server’s internal routing.
• Messages Quarantine
It may be that most mail is being delivered successfully but some mail
messages are being filtered. Check your user’s quarantine to see if the
messages are there. See Manage Quarantined Messages for more
information about how to view and modify quarantines.
• After Troubleshooting
After you’ve followed these steps, send another message from an outside
server (such as your personal Gmail address) to confirm that the problem has
been resolved.
