Hello everybody!
Since our company uses ESAs we are thinking about utilizing SenderBase for a better filtering of unwanted mails.
Now I aimed to find out what data is sent to SenderBase when doing a query. I found this page:
http://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/118408-technote-esa-00.html
which tells me that "queries disclose several things about your Company". After that it says that 1) parts of the system serial number and 2) the IP adresses connected to our ESA, are disclosed.
My question is: are these two pieces of information the only ones sent to SenderBase or is there more disclosure. The phrase "several things" makes me hesitate...
Thank you very much!
