Which feature must be activated on a Cisco Secure Email Gateway to combat backscatter?

Show Suggested Answer Hide Answer
Suggested Answer: B

A regular expression is a sequence of characters that defines a search pattern for text. To match a string of 123ABCDEFGHJ, you need to use the following regular expression: d{3}[A-Z]{9}. This expression means that the string must start with three digits (d{3}), followed by nine uppercase letters ([A-Z]{9}). This expression will match any string that has the same format as 123ABCDEFGHJ.

I'm leaning towards Forged Email Detection. Seems like it would be able to catch those pesky spoofers trying to bypass the system.

Hmm, I think Bounce Verification is the way to go. It sounds like it would be the most effective in combating backscatter, right?

But wouldn't Bounce Verification help verify the legitimacy of bounce messages?
