The IP whitelist allows you to whitelist emails from specific IP addresses or IP address ranges. Emails from these IP addresses are ignored by ORF, so you can guarantee that specific senders can always send emails to you. Use this list to whitelist the outgoing email servers of your business partners.
The list is available under in the left navigation pane.
Set this checkbox to whitelist emails from our email servers. This option is enabled by default to avoid rejecting important emails from us, such as replies to your support inquiries, registration or update information.
Click the New button to add an IP address or IP address range to the list. To modify an existing address definition, click Modify or hit Enter. IP address definitions can be deleted using the Delete button or the Delete key.
Click the Test button to invoke the Test IP Address Dialog, which can be used to quickly identify any entry matching the IP address you entered. This comes in handy if you want to identify which entry excluded a sender from blacklist tests (to avoid false negatives in the future), or if you want to make sure your current entries do not whitelist a specific IP address.
For more information about this dialog, please consult the Test IP Address Dialog section.
Click the column header of any column by which you wish to sort the IP Whitelist. To reverse sorting, click the column header again.
Right-click on the address list and select "Import list..." or "Export list..." Alternatively, you can do this from the menu by selecting or .
See the IP Address Editor Dialog topic.
Before Arrival, the IP address checked is the incoming SMTP connection remote peer IP address.
At the On Arrival filtering point, ORF analyzes the delivery path of the email, which is stored in the email header. During this analysis ORF determines the sender IP based on your Intermediate Host List settings: it tests the first non-Intermediate Host against the IP Whitelist.
For more information, see the Header Analysis and Intermediate Host List sections.
