Attached message/rfc822 not shown when Content-Transfer-Encoding: base64
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; de-AT; rv:1.7.5) Gecko/20041217 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; de-AT; rv:1.7.5) Gecko/20041217 A body part of "Content-Type: message/rfc822" is not shown when this body part has "Content-Transfer-Encoding: base64". PMmail (http://www.pmmail2000.com) produces such body parts. Besides PMMail itself, The Bat!, MS Outlook Express, KMail (Linux KDE), and the T-Online webmail client do show such attached message without problems. BTW, the previw of that body part also remains blank. Reproducible: Always Steps to Reproduce: 1. Receive a message with such an attachment 2 [review]. Open the message 3. Klick on the attachment button Actual Results: A window is being opened for the attached message, but the area where the content of the attached message should appear, remains blank. Expected Results: Should have decoded the body part and shown it as a message.

The Thunderbird version used is 1.0.2 The example message shown in the description should probably have been created as an attachment to this bug report... L.W.
Invalid? RFC 2046, "5.2.1. RFC822 Subtype" says ; ( http://www.faqs.org/rfcs/rfc2046.html ) > 5.2.1. RFC822 Subtype >(snip) > No encoding other than "7bit", "8bit", or "binary" is permitted for > the body of a "message/rfc822" entity.
Reorter, does "Save As" of the attachment(the base64 encoded message/rfc822 part) work?
Yes, I can save the attached message, but it is not decoded, but remains Base64 encoded. As to the quote from RFC2046 -- OK, I have read that before. But, you see, the attachment _is_ encoded as binary (i.e. Base64), and also one should follow the old rule: be strict on sending, be very generous on receiving. So, there _are_ eMail-Clients out there which do encode each and every attachment in Base64, and all the clients which I had tested, except Thunderbird, were able to decode the message. Does anybody want to receive such a message with an attachment message encoded as Base64? Mail a request to my mailbox, and you get an appropriate answer. Yours, L. Willms

Good grief... > one should follow the old rule: be strict on sending, be very generous on receiving. I agree with you. But "displaying mail of RFC violation" and "saving base64 encoded attachment with decode" are different issues. I recommend you to open enhancement request bug for the new issue - Request for saving attachment with decoding even when violation of RFC if Content-Transfer-Encoding is binary - base64 (quoted-printable also excluding CR/LF).
(In reply to comment #5) > (In reply to comment #4) > But "displaying mail of RFC violation" and "saving base64 encoded attachment > with decode" are different issues. I don't think that this is a violation of the MIME-RFC. And both the non-display and the non-decoding on save are both caused by not decoding the body part. Thunderbird should simply comply and decode according the a possible "Content-Transfer-Encoding" header in the body-part header, and not do a preselection based on Content-Types. Yours, L.W.
