Add more fields to Content-Disposition header field in outbound MIME message

Currently when Notes Client or iNotes send out a MIME message to external domains, then they include the fields in Content-Disposition header of MIME source (for attachment description) as below.

Content-Disposition: attachment; filename="TestAttachment.pdf"
Content-Transfer-Encoding: base64

This Content-Disposition header from Notes Client or iNotes currently does not include other field like size, creation-date, modification-date etc.These fields are defined in RFC 2183. The example of Content-Disposition header is shown below.

https://tools.ietf.org/html/rfc2183

Content-Disposition: attachment; filename="TestAttachment.pdf"; size=15294; creation-date="Wed, 26 Dec 2018 09:34:59 GMT"; modification-date="Wed, 26 Dec 2018 09:34:59 GMT"
Content-Transfer-Encoding: base64

So there is a feature request to add the fields size, creation-date, modification-date in Content-Disposition header of outbound MIME message from Notes Client and iNotes.

This Enhancement Request is submitted for V9 and V10 version.
