MIME Header Filters

The MIME Header Filters will search e-mail attachments for specific patterns. This will search the attachment by filename or file extension and has the ability to block the e-mail or log and deliver it.

To create a MIME Header Filter click the fine Define New MIME Header Filter link. A new window will appear with the option to create the pattern.

Match Type

The chosen pattern will be matched against either the Filename or the File Extensions.

Pattern

This is the pattern that will be used to match against the Match Type. A complete filename or just the extension can be entered here.

Action

When an e-mail matches the pattern it will take action against it. The pull-down menu contains the options Reject Message and Log Warning.

Message

When an e-mail matches the pattern and the action is taken, the contents of this Message field will be used in response. If Log Warning was chosen as the Action then this message will be stored in the logs. If Reject Message was chosen as the Action then this message will be sent to the sender of the mail and stored in the logs.

This Message field is not required to create the filter.

Once all the fields have been completed click Create Filter to create the filter. Once created, the filter will appear on the menu under MIME Header Filters. As with the Header Filters mentioned earlier, the MIME Header Filters are listed in the order of their priority. Filters configured to reject e-mails will be highlighted in red and filters configured to only log them will be highlighted in green.

To edit or delete a pattern click the Edit link located to the left of the filter. This will open a new window displaying the content of the pattern. Changes can be made to this and saved by clicking the Update Filter button. It can be deleted by clicking the Delete Filter button.
