What should I do if the MX record test fails after just
changing my MX records?
If your MX Record Test failed, the test’s error message gives you troubleshooting
information. For more information about the error message, see Error Messages
and Next Steps in the “MX Record Test” chapter.
What do I do if my mail is not being delivered?
There are several things that can impact your mail flow:
1. Confirm your Delivery Manager configuration is correct. For information, see
Verifying Email Flow.
2. Make sure your MX records are pointing to the correct system cluster. For
finding your system cluster, see IP Range.
For more MX record information see the Activation Step-by-Step Guide’s How
MX Records Work FAQ.
3. Follow the troubleshooting mail flow instructions in Why am I not getting any
mail at all?.
Notifications and Alerts
Do I need to verify a notification address?
Yes, as good practice, you need to verify these addresses. The email security
service does not validate the notification address. But if the receiving mail server
has been configured to check the validity of the sending address that could cause
your notifications to fail.
What should I do when my notifications fail to be delivered?
Some suggestions are:
• Check to see if your mail server has had any recent filter changes.
• Check to see if any of your mail server’s spoofing filters are blocking the
notifications.
