[Zope] Mailing List management: corrupted message headers in digests

[Dieter Maurer]

Dear mailing list administrators

at least the digests have some deficiencies:

 1. some message headers are corrupted (do not use RFC822
    continuation style).
    Example is: Zope-Dev digest, Vol 1 #517 - 17 msgs"
                Message: 10
                From: "Kevin Dangoor" <kid@kendermedia.com>
                To: "Fabio Augusto Mazzarino" <mazza@radiumsystems.com.br>,
                <zope-dev@zope.org>
                Subject: Re: [Zope-dev] Turn-off undo.
                Date: Tue, 16 May 2000 10:13:29 -0400
                charset="iso-8859-1"

    The "To:" header continuation line is not indented as it
    should be by RFC822.

 2. the digest removes MIME headers.
    They are, however, vital, e.g. for multipart messages.

 3. MIME header removal seems to be incomplete, leading to
    corrupted message headers.
    See the example above, where obviously the "Content-Type:"
    header has been removed, but its parameter "charset="iso-8859-1"
    was retained.

 4. Many messages get truncated by RFC934 bursting,
    apparently, because they contain lines beginning with "--".
    As far as I understand RFC934, such lines should be
    prefixed with "- ".
    Example: Zope-PTK digest, Vol 1 #127, message 8
             Message: 8
	     From: "Kevin Dangoor" <kid@kendermedia.com>
	     To: "Tres Seaver" <tseaver@palladion.com>
	     Cc: <zope-ptk@zope.org>
	     Subject: Re: [Zope-PTK] Adding LoginManager at the root
	     Date: Tue, 16 May 2000 10:53:26 -0400
	     charset="iso-8859-1"

    RFC934 bursting creates a message with empty body.

 5. similar problem as 3 for "References:" header:
    Example X-Digest: Zope digest, Vol 1 #783 - 36 msgs
            Message: 35
