> We, at Linagora, use Headers to pass information from James to other subsystems. Such example can be found as the ICALToHeader mailet.
> However, this introduces a vulnerability: someone can send a mail with these headers, and pretend some processing happened in our James instance. To avoid this, we strip such header. 
> But every time we add a new header, we need to add a new RemoveMimeHeader Mailet parameter from stripping. This is error prone.
> We would like the removal to be doable by prefix: this way, if all of our specific share a common prefix, we don't need to review configuration every time we add a feature. 
> Thus:
>  - RemoveHeaderByPrefix allow removal of you prefixed header
>  - HasHeaderWithPrefix allow you to report emails using your internals prefix, to potentially take further actions
