URL Domain Black List
How to get hereUse URL Domain Black List to search for domain names that appear as URL links in messages and set the action to take on such messages. Secondary mail domains can choose to use the primary domain's URL Domain Black List instead of maintaining their own.
The URL domain black lists for the current mail domain is stored in the url-domain-bl.txt file, which is located in the IMail top directory.
Domain: Shows the current selected domain. From the drop down you can pick any of the domains available to this administrative user account.
Use: Set the following options to configure HTML features filtering.
- No Filtering. Disables URL domain black list filtering for the selected mail domain.
- Current Domain (selected by default). Select this option to define URL domain black list filtering settings specific to the current mail domain. The primary mail domain selects this option to use the primary URL Domain Black List. The secondary mail domains select this option to use the secondary mail domain's URL Domain Black List.
- Primary Domain (default for non- primary domains; not available for primary domains). Select this option to use the primary mail domain's URL domain black list filtering instead of creating new settings for the current mail domain.
Note: Because secondary mail domains cannot add or remove words from the primary mail domain's URL domain black list, if you are setting URL domain black lists for a secondary mail domain, the Add and Delete buttons are disabled for the selected secondary mail domain and the URL domain black list cannot be edited.
Scan. Set the following option to configure the type of text that domain black list filtering scans for hyperlinks (URLs):
- HTML text. Select this option to scan HTML text for hyperlinks embedded in e-mail messages. Example
- HTML and Plain Text. Select this option to scan both HTML and plain text for hyperlinks embedded in e-mail messages. Example
Action taken on e-mail determined to be spam. Specify one of the following actions to take on a message that matches a URL Domain Black List:
- Action:
- Delete. Immediately deletes the message.
- Forward to Address. Forwards the message to the e-mail address specified in the text box to the right of this option. By default, messages are sent to the root address and stored in a mailbox called "root- bulk". Example
- Insert X- Header (default). Inserts an X- Header into the message indicating that it was identified as spam and includes a matching black list. See also X-Header Explanations.
- Move to Mailbox. Moves the message to the user's mailbox specified in the text box to the right of this option. If the mailbox does not exist, it is created. The default mailbox is "bulk".
- None. No action is taken on the message.
- Prefix Subject With. If selected, the subject of a message that is identified as spam by the URL domain black list filter will be modified to begin with the text entered in the text box.
To Edit a URL Domain Black List:
- From the URL Domain Black List page, click Edit Phrases URL Entries. The URL Domain Black List Text Editor page appears. The File information displays the file directory where the
url-domain- bl.txtfile is saved. - Enter the name of the domain or IP address that you want to add to the black list. See below for acceptable entry guidelines. Press Enter after each phrase is entered in the text editor.
- Click Save.
Acceptable Entries
If you enter the domain name in the format of www.domain.com , a URL must contain the entire entry (including www.) in order for the message to be identified as spam. Messages with only domain.com in the URL will not be identified as spam. Example
If you enter a domain name in the format of domain.com, IMail Server looks for all URLs that contain domain.com, whether or not it is preceded by anything. For example, the URLs www.domain.com and www.mail.domain.com would both be identified as spam, because they both contain the entry domain.com.
