To enable greylists, use the following command in configuration mode:
hostname (config)# web-analysis greylists enableNote
If you skip this requirement, the Web UI Settings tab does not include greylist options.
Create a greylist text file that contains the URLs or IP addresses (or subnets), one item per line. The greylist must be hosted on a server and accessible using HTTP, FTP, TFTP, or SCP. See Example: Greylists .
Note
File names can include the following characters: letters (a-z, A-Z), numbers (0-9), underscores (_), periods (.), plus and minus signs (+, -), single quotes (‘), and left and right parentheses. Any other characters are replaced with the minus (-) sign. For example, if the name of the file you upload is hello%hello.doc, then it will be renamed and stored on the appliance as hello-hello.doc.
