4. Security Considerations

Security considerations are not discussed in this memo. However, law enforcement officials might wish to consider the possibility that this mechanism could be used by criminals, either to escape extradition by mailing themselves outside of a legal jurisdiction, or to outwait the statute of limitations by mailing themselves through complex mail routes with long delays. (One supposes that they could also look on the bright side, and consider MIME as a possible approach to solving the long-standing problem of prison overcrowding.)
