Chapter 13 SenderBase Network Participation
Will sharing data impact the performance of my IronPort appliances?
IronPort believes that there will be a minimal performance impact for most
customers. We record data that already exists as part of the mail delivery process.
Customer data is then aggregated on the appliance and sent to SenderBase servers
in batches, typically every 5 minutes. We anticipate that the total size of data
transferred via HTTPS will be less than 1% of the bandwidth of a typical
company's email traffic.

When enabled, the Context Adaptive Scanning Engine (CASE) is used to collect
and report the data (regardless of whether or not IronPort anti-spam scanning is
enabled).

Note
For C30 and C10/100 appliances, if you choose to participate in the SenderBase
Network, a “body scan” is performed on each message. This happens regardless
of whether a filter or other action applied to the message would have triggered a
body scan. See “Body Scanning Rule” in the “Using Message Filters to Enforce
Email Policies” chapter of the Cisco IronPort AsyncOS for Email Advanced
Configuration Guide for more information about body scanning.

Are there other ways I can share data?
For customers that want to share additional data to do even more to help IronPort
provide top quality security services, there is also a command that allows this.
This higher level of data sharing will also provide attachment filenames in clear,
unhashed text, as well as hostnames of URLs in messages. If you are interested in
learning more about this feature, please talk to your Systems Engineer or contact
IronPort Customer Support.
