Domain Virus Processing Rule (Avoiding potentially harmful emails )

Definition: Harmful email usually takes the shape of email with attachments containing certain extensions.   

This practice should be used with great care and if you plan on receiving email with these types of attachments this rule will not enable the mail to go through.

Using your Web Panache E-mail interface, you are able to filter attachments that contains specific file extensions ie. .exe .vbs .js .scr .

1. Access your E-Mail Administration Interface using your Administrator ID (e.g. root@yourdomain.com).

2. From main page, click the "Administrative Account Options"  select box and then click "Domain Processing Rules".

3. Click the "Add Rule" link on the right side of the screen.  The Add a Rule screen displays.

4. Select the  "Field:" Body , and check the "contains" (yes) radio button.  The mail server considers attachments as part of the body of the email document.  It will then scan the attachment for the following rule.

5. The Phrase: text area should contain this string (copy and paste):
   (name=".*\.vbs"\s|name=".*\.shs"\s|name=".*\.scr"\s|name=".*\.exe"\s|name=".*\.data"\s)
   
   If you would like to add/remove  file extensions be sure not to break the pattern of the string.

6. To automatically delete filtered messages, select <delete> in the "Move to:" field.  To automatically send filtered messages to a new mail box, select <new> and type the name of the name of the mail box in the field next to your option, i.e. Spam or Virus.

7. Make sure that you do not have the Case sensitive match or Search String From File  checked.

8. Finally, click the "Add" button on the bottom left corner listed Add.

9. Verify that the filtering rule you added is listed in the Existing Rules table. It should look something like this:
