Hi Ken,
Content-Disposition: =?utf-8?Q?inline?=
...
It seems, however, we should simply follow RFC 2183 and treat it as an
"unknown" disposition (which means "default as attachment").
I disagree. :-)
Given RFC 2183's grammar,
disposition := "Content-Disposition" ":"
disposition-type
*(";" disposition-parm)
disposition-type := "inline"
/ "attachment"
/ extension-token
; values are not case-sensitive
coupled with RFC 2045,
extension-token := ietf-token / x-token
ietf-token := <An extension token defined by a
standards-track RFC and registered
with IANA.>
x-token := <The two characters "X-" or "x-" followed, with
no intervening white space, by any token>
that field does not parse so RFC 2183's
Unrecognized disposition types should be treated as `attachment'.
does not apply as we do not have a disposition type, recognised or not.
