Public bug reported:
Mailman tarballs contain a Defaults.py file with this configuration:
NOTE: I don't know how this file is generated, I found it on the
tarballs but not on the repository
So, when someone enables filtering on a mailing list by mime-type, the
default is to filter all emails not matching any of those 3 mime-types.
This list of default mime types allowed misses to include
Therefore, this is unfortunately filtering any "multipart/signed"
"multipart/signed" is defined on RFC 3156
<https://tools.ietf.org/html/rfc3156> and is the recommended way of
signing mails with GPG. See http://wiki.gnupg.org/SignatureHandling
The proposed change is to modify that default configuration to:
DEFAULT_PASS_MIME_TYPES = ['multipart/mixed', 'multipart/alternative',
'multipart/signed', 'text/plain', ]
This default causes trouble to people that signs their mails with GPG. I
already had problems due to this default on the Alioth Debian mailing
lists and on the WebKit mailing lists because the admin enabled
filtering by mime-type and didn't changed the default.
Please, change this default by adding at least 'multipart/signed' to the list of types allowed.
