[Dovecot] Sieve problems (not matching emails expected to match)

[Michael Welsh Duggan]

I have a sieve file that reads like this:

require "fileinto";

# Emacs
if header :contains "List-Id" "emacs-devel.gnu.org"
{
    fileinto "mail.emacs-devel";
}
elsif header :contains "List-Id" "emacs-bidi.gnu.org"
{
    fileinto "mail.emacs-bidi";
}
...

Unfortunately the List-Id based lines don't appear to be working,
although some other ones do.  The attached test message does not get
delivered to the mail.emacs-devel list.  Why?
