Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
The variable message-fcc-externalize-attachments seems to have no effect
(tested in emacs 30.0.50). Whether I set it to t or nil, whenever I send
a mail message with a file attached, the file is included as an internal
message part in the FCC mailbox.
I am not sure if this is a bug or if I am missing something, such as
another variable that interferes with this one.

I'm trying to figure out what "externalization" is actually supposed to
do.
So far I don't see that this option would actually do anything in an FCC
context. `message-fcc-externalize-attachments' is only used in
`message-do-fcc`, where its value is let-bound to
`mml-externalize-attachments'.
But `mml-externalize-attachments' is only consulted in
`gnus-inews-do-gcc', which already doesn't sound very promising. That
function first let-binds `mml-externalize-attachments' to nil, before
doing its own setting, so any dynamic value is getting overridden
anyway.
I tried starting with `gnus-gcc-externalize-attachments' and sending a
message with an attachment, just to see how it's supposed to work.
Nothing seemed to happen.
Can you tell me what the desired effect is supposed to be? Does the
"gcc" version of this option work for you?

I guess you are asking Nicolas, not me? Because I don't use these
features (and don't use message.el at all).
Nicolas, can you please answer Eric's question?

When you attach a file to a mail message you are writing, only an anchor
with the file name is inserted in the message buffer. When the message
is sent, the anchor is replaced with the actual MIME-encoded contents of
the attached file. The copy of the message that is written to the FCC
file also includes the MIME-encoded attached file.
I was expecting that externalization would mean that the copy in the FCC
file would only include an anchor rather than the attachment, which
would be extremely useful. I must admit this was only a guess (wishful
thinking?) since the documentation is not explicit at all.
I don't use gnus. To test the gnus version of the variable, I guess I
would need access to a free, public NNTP server, which I don't know
where to find. Can you help?

Oh, that sounds very useful, I've often wanted that.

I think most of us use news.gmane.io
I tested the GCC version again (now that I know what it's supposed to
do), and it did work -- the version of the message in my Sent folder had
a mime part of "message/external-body".
Long story short, the encoded body of the message is cached during
sending, and the cached version is re-used during GCC/FCC handling. If
the user has requested the externalization of attachments, the GCC
version of the code knows to use that as a flag to dump the cache and
re-generate it with externalized attachments; the FCC code doesn't do
the equivalent.
I've pushed a change that fixes this issue in my testing -- are you
using Emacs master? If not, I've attached the commit here, I hope you'll
be able to test it.
Thanks,
Eric
