Problems with a mailbox in Rmail format

Problems with a mailbox in Rmail format

[Pascal Quesseveur]

Hello,

I have saved some messages from Gnus to a mailbox in Rmail
format. When I open the file in rmail-mode messages are not displayed
as expected: they are displayed in full, no headers are removed, MIME
parts are not handled, ... It seems to me problems come from the fact
mail headers in the mailbox are capitalized and rmail-mode search and
match operatinos are case dependant. I have set an advice around
(rmail-show-message-1) to set case-fold-search to t and problems
disapeared.

I am wondering if the problem can come from my configuration or if it
is an error in my version of Emacs (checked with Emacs 24.3.1 and
24.5.1.).

case-fold-search is t by default.  Did you change the default?

Which operation in rmail-show-message-1 depends on letter-case of the
headers?  In general, Rmail uses mail-fetch-field to get the headers,
and tha function explicitly binds case-fold-search to t.

Yes. I forgot it was changed to t.

Yes, this is true for mail-fetch-field. But in my version
rmail-show-message-1 checks for mime by searching directly
"mime-version: 1.0". And I think headers set in rmail-ignored-headers
are also checked as they are.

Oups.

                                    nil.

Please report this as a bug, preferably with a small mbox file that
can be used to reproduce this.

Thanks.
