This was actually standardized in RFC1327 (and partially deprecated in its followon, RFC2156). It's a way for X.400 gateways to represent service elements not available in RFC822. In X.400, one could specify options like "Receipt Notification Requested" and "Reply Requested" on a per-recipient basis. An RFC2156-compliant gateway would append these options to each address as a comment.
