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?

Nicolas
