Configuring IP filtering for an FTP mailbox

Whitelist IP addresses are entered on the IP Filter tab of each local user mailbox. These IP addresses are the only addresses that will be allowed to log into the mailbox.
  1. Go to the IP Filter tab for your FTP mailbox.
  2. Click New to create a new entry or double-click an existing entry to edit it. Alternatively, you can right-click on the entry and select Edit.
  3. Enter an IP address to be added to the whitelist.
    You can use both IPv4 and IPv6 addresses. IP addresses can be a single address or a range of addresses. The following are examples of valid IP addresses:
    IP Address Description
    * All IP addresses
    10.11.12.13 Single IPv4 address matching 10.11.12.13
    10.* IPv4 addresses in the range 10.0.0.0-10.255.255.255
    10.11.* IPv4 addresses in the range 10.11.0.0-10.11.255.255
