This section describes the use of the signature idetifier lists in ORF.
Sender/signature identifier lists allow you to define a list of sender and DKIM selector-domain masks.
Set the checkbox on the top to enable, or clear the checkbox to disable the list. Note that this option may not be available for all sender/signature identifier lists.
Click the New button to add a new sender-selector-domain expression to the list: this will invoke the Sender/Signature Identifier Dialog. To modify an existing expression, select it and click Modify or hit Enter. Expressions can be deleted using the Delete button or the Delete key.
When entering domains, the http:// https://, ftp:// etc. prefixes MUST not be added.
When working with IDNs, make sure to enter these in ASCII ("Punycode") format, e.g. as "xn--e1afmkfd.xn--80akhbyknj4f" instead of "пример.испытание".
Click the column header of any column by which you wish to sort the sender/signature identifier list. To reverse sorting, click the column header again.
Click the Test button to invoke the Test Sender/Signature Identifier Dialog, which can be used to quickly find any expression matching the sender-selector-domain triplet you entered. This comes in handy if you want to identify which manual expression blocked a legitimate sender (to avoid false positives in the future), or if you want to make sure your current expressions do not whitelist or blacklist a specific sender or domain.
For more information about this dialog, please consult the Test Sender/Signature Identifier Dialog section.
Right-click on the list and select "Import signature identifier list..." or "Export sender/signature identifier list...". Alternatively, you can do this from the menu, select or
The import and export format for the sender/signature identifier definitions is XML (see the List Import and Export Formats section).
