Specialized Filtering

A new page on the configuration menu, Specialized Filtering, contains a feature that removes attachments with a particular filename/MIME content-type from email messages and replaces them with a configurable notification text message. Sender, recipient(s), and/or administrator(s) can be notified of the attachment removal.

Specialized filtering policies are created on the Specialized Filtering/Set Policy page in the same way as content filter policies with some exceptions:

1.    You cannot configure the action.

2.    All attachments are stripped (removed) from the message if it matches the policy.

Note: Please see Creating a Content filter Policy for a description of the procedures.

Applying the Rule

You can apply two basic conditions for the rule. Apply the rule when it matched the conditions or apply the rule when it does not match the conditions. This allows for a great deal of flexibility when creating the rule.

Attachment Removal

1.    You can remove file/MIME content types from inbound messages, outbound messages, or both.

2.    Filenames can include wildcard characters. For example, "*" will remove all attachments, and "*.exe" will remove all executable (.exe) attachments. Separate multiple file names with a comma.

3.    You must specify either a filename or a MIME type. eManager will not filter file names and MIME types in the same policy. If you wish to filter for both filenames and MIME types, you will need to create an individual policy for each.

Configuration

1.    Use the Specialized Filtering/Configuration page to enable the policy. The enable Specialized Filtering box must be checked for the policy to go into effect. You can have copies of the original messages with all attachments put into the quarantine directory. The quarantine directory is defined on the Advanced Options tab.
