The tarballs we distribute do not contain Mailman/Defaults.py. They and
the lp:mailman/2.1 branch contain only Mailman/Defaults.py.in.
Mailman/Defaults.py is generated by configure by applying various
configure options and defaults to Mailman/Defaults.py.in.
Also, in Python,
DEFAULT_PASS_MIME_TYPES = ['multipart/mixed', 'multipart/alternative',
'multipart/signed', 'text/plain', ]
and
DEFAULT_PASS_MIME_TYPES = ['multipart/mixed', 'multipart/alternative',
'multipart/signed', 'text/plain' ]
(without the last comma) are equivalent.
Now, as far as the actual bug is concerned, I am unsure as to the best
default for pass_mime_types. I agree that various multipart subtypes
such as multipart/related and multipart/signed should be accepted so
their text/plain sub-parts will be accepted. To this end, I think at a
minimum we should have
DEFAULT_PASS_MIME_TYPES = ['multipart', 'text/plain']
to accept any text/plain subparts of any multipart type, but this brings
up other questions. Namely, should we accept message/rfc822 parts to
ultimately accept text/plain parts from attached (forwarded or ?)
messages, and if we are accepting multipart/signed, should we also
accept the actual signature.
For the former, I think the answer is yes. The latter is more
complicated because application/pkcs7-signature parts are binary so in
the spirit of only accepting text/plain, perhaps we should only accept
application/pgp-signature signature parts. I'm tending towards
DEFAULT_PASS_MIME_TYPES = ['multipart', 'message/rfc822', 'text/plain',
'application/pgp-signature']
but I'm continuing to think about it.
