4. Retrieve the test message sent to your administrator’s Inbox.
When this test is successful, a test message is delivered to your administrator
address. It’s important that you are able receive this message. If you don’t
receive it, look under “Frequently Asked Questions: Test Filtered Mail Flow”
on page 46.
Frequently Asked Questions: Test Filtered Mail Flow
How can I tell my email is being filtered?
The Administration Console has real-time charts and graphs displaying current
email activity at the message security service’s data center, including messages
filtered as spam or viruses, and messages delivered to your server. After email
has begun to flow through the data center for your administrator address, go to
the Console’s home page to see this activity.
What if I don’t receive the test message?
If your test succeeds but you don’t receive the test message, your firewall or mail
server might have an anti-spoofing feature turned on. To proceed, turn off any
email filtering which prevented spoofing and run the test again. For information on
configuring spoofing, consult the product documentation or support resources for
your firewall or mail server. The message security service will provide
comprehensive filtering against spam, so spoofing protection at your mail server
is not needed.
When the message security service’s data center sends a Welcome message
(and other notifications), it “spoofs” the sender address to make it look like it came
from your support address. That way, users feel they are interacting directly with
you. To proceed with activation and use your service in general, please turn anti-
spoofing off and leave it that way.
