Tag or reject email with invalid message content transfer encodings as given by RFC 2045. For example a message that is declared to use MIME 7-bit encoding, but contains an 8-bit octet, NUL byte, and/or unpaired CR or LF characters, would be considered invalid and tagged/rejected. Variations of these checks are performed for MIME parts with 8-bit or binary encodings.
