Yes, you can use TrustedSource to filter out spam. You can read about TrustedSource in the knowledgebase, article # PD21526.
If you would like numbers you will have to contact a Sales person at 1-800-379-4944, option 3 (or just call your Sales person directly). They may have some numbers for you. I looked at our Data Sheet from McAfee.com but I couldn't find any anti-spam numbers.
No Firewall enterprise v8 is not an antispam.
Reduce risk from threats on your network
Put the firewall in charge of network security again with integrated comprehensive network protection technology, including:
- Network intrusion prevention
- Web filtering
- IP reputation
You've IP reputation but it's not enough for an antispam.
Trusted Source (Network Reputation) is not traditional anti-spam, but we have many customers who use it as a compensating control in front of their mail gateways. Most customers see about an 80% drop in spam when they enable trustedsource on their inbound mail. TrustedSource has also demonstrated an ability to prevent many zero days attacks that use e-mail as the initiating threat vector. All of this comes at minimal resource cost to the firewall, which is not the case with most anti-spam solutions that do complicated heuristics and consume significant resources. If you are looking for a full anti-spam solution I would recommend McAfee E-mail Gateway, and use TrustedSource on the Firewall to cut a large percentage of your spam.
The combination of Trusted Source, Geo-Location and a thoroughly configured mail server blocks 90-95% of spam for me.
