The disclosure of the current invention describes a method of handling a message or a document to be released external of a secure computer environment. The message or the document is first directed to a trusted sealing device which displays the message or the document to a human user for visual checking. If the message or document is acceptable to the human user, the method associates the message or the document with a seal produced by the trusted sealing device. The message or the document is then directed along with the associated seal to a gateway which deletes portions of the header and checks the validity of the associated seal. If, as a result of this verification, it is determined that the associated seal is validly associated with the message or the document, the method attaches predetermined header portions to the message or document and communicates the message or the document from the secure computer environment.
