With curl 7.56 , multi form post have some discrepancy in sending the

If no special content disposition is set by the caller, libcurl sets it
as "form-data" if the parent part has content type
"multipart/form-data", else "attachment".
You can force another content disposition by forging the full header
yourself and setting it in the part, as it is done in
https://github.com/curl/curl/blob/master/docs/examples/smtp-mime.c#L127.
In that case, the field name and filename set for the part are ignored.
I have no global view of what you are doing and of your mime structure:
I can imagine you use the mime API and the context is not HTTP (probably
SMTP or IMAP) or the part is a subpart of the parent part that has not a
"multipart/form-data" content type. This later case is not standard.
If you still use the form API, individual multiple file field parts
always add a content disposition of "attachment" since the parent part
(the one that represents your field) is not of content type
"multipart/form-data".
