From the SMTP proxy action settings in this image, which of these options is configured for outgoing SMTP traffic? (Select one.)
A. Rewrite the Mail From header for the example.com domain.
B. Deny incoming mail from the example.com domain.
C. Prevent mail relay for the example.com domain.
D. Deny outgoing mail from the example.com domain.
I think that the right is C
You can also use the Rewrite As or Replace option in a rule to configure the Firebox to change the Mail From and Mail To components of your email address to a different value. This feature is also known as SMTP masquerading. For example, you can create a rule for the Mail From or Rcpt To to replace olddomain.com with newdomain.com.

I think the correct answer is: A
The answer is C. This was one of the questions on the white paper from watchguard (example exam questions). The question was worded as follows.
What rule in the SMTP-Outgoing proxy action can you use to prevent spam relay through your email server?
a. Rcpt To
b. Mail From
c. Headers
d. Authentication
e. Greeting Rules
Answer: B
B is the answer … mail from is incoming mails
How can the answer be ‘B’ ? This is an outgoing rule. So it is saying outgoing mail cannot come from *@example.
LOL, Study harder!
