postfix

I want to setup postfix so that email lacking a specific email header are rejected.

Is it possible to use header_check to reject emails that do not include a specific header field entry.

The solution that I believe may work is the following:

/^x-tituslabs-classifications-30: (<>)?$/ REJECT Classification field required

I want to make sure that any email going through postfix contains a x-tituslabs-classifications-30 entry.
