The topics in this section provide answers to frequently asked questions about the Policy Rules for Forefront Online Protection for Exchange (FOPE). This is not a comprehensive list of questions and can be supplemented with information from Policy Rules and its related topics.

A. There is no limit on the number of policy rules you can create.

A. Policy rules generally take 30 to 35 minutes to replicate.

A. Test Rules are used when an administrator wants to check how a policy rule will work without affecting the message traffic to or from the domain. Any message that would have triggered the rule will be delivered normally and appended with a rule-specific flag notifying the recipient that it would have been blocked if the rule was not in Test Mode. Test Mode notifications can be inserted into either the X-header of a message or in the subject line with the policy ID. A BCC can also be enabled if an administrator wishes to receive a copy of the messages for troubleshooting purposes.

A. Yes. Through the use of Regular Expression syntax, you may use wildcards in almost every field in the policy rules UI. For details, see Understanding Policy Rule Syntax.

A. Yes. When creating your policy rule, select the “Search files in compressed attachments” checkbox in the Attachment area.

By default, this check box does not apply to password-encrypted files. To permit password-encrypted files to pass through the Hosted Filtering network, you must insert ZIP+ in the Attachment file extensions box. If you do not select this check box, and any file extension that you want filtered by the policy rule is contained in a non-password-protected archive file, the archive file will be scanned for viruses, if your contract includes virus filtering. If no virus is found, the message will not be matched.
