If you're seeing something I can't, paste it into a reply: there's probably nothing I can do but why not share the frustration? FWIW Thunderbird is the only newsreader that does this, all others decode the files correctly, but that's no help to you. I don't know what Turnpike's default settings are, but somewhere you should be able to ensure that the encoding information in the header is correct. It doesn't allow MIME in news posts, only in mail! I've found Windows 7 home edition easy to live with except that the last-ever version of Turnpike's incompatible with it and this version's too primitive. I've tried other newsreaders but they didn't meet my needs. I can still open the pictures if I Save As the message on the desktop as a *.jpg file, and open it from there, but it would be more convenient to see the image when I open your post. I know. I get that with M$ Office files. I like the back-lighting, BTW. ;-) Thanks - though maybe I should post some rubbish so that you can just killfile me! HTH I'll see if anyone's in the pub tonight who's old enough to remember how Usenet works. Something might come of it. -- Sue ] |

Joevan's and Pat's pictures decode correctly. I see an image in the message pane, and also as an attachment (the file name displays in the attachment bar). In this case, your pictures did not show as attachments. Tbird obviously believes the message header (which identifies the encoding as mime), and not the file header (which identifies it as uuencoded). So it doesn't even try to decode the image file. Don't worry about it, Sue, I'm quite willing to do the Save As then Open thing. TBird cannot combine multi-part files, which is occasionally an issue. It's also unreliable when decoding yEnc encoded messages, which doesn't bother me. Have a good day, Wolf K. |

If there are enough "malformed" messages out there, the bug will be fixed. Interesting: my expert says nothing in the message header relates to attachments. What matters is the blank line followed by 'begin 664 filename' (or 'begin 666 filename' if you have a Microsoft emanation) and the end markers. That means if you attach one UUencoded and one MIME encoded file to a message they should both be decoded successfully. I'd like to try that in an e-mail to Thunderbird since I can't try it in news; I haven't time just now but will try to remember it when I return home... Happy snapping -- Sue ] |

What matters is the blank line followed by 'begin 664 filename' (or 'begin 666 filename' if you have a Microsoft emanation) and the end markers. OK, I'll try to explain what's going on. Bewar with me. ;-) In your message there are two lines: "begin 644 zCistus01.jpg" That's the file type, and it will be there whether the image is attached or "in-line". But it is the file type, _not_ the encoding type. The encoding applies to the message as a whole. (1) Before that there's "[ Section: 1/1 File: zCistus01.jpg UUencoded by: Turnpike Integrated Version 5.02 S ]" That refers to a message encoding method. It should be in the message header, but there I find: "mime-version: 1.0" That refers to the encoding of the message as whole, attachments and all. Since there is only one section (the jpg image) there's only one line referring to the encoding method. The problem is that Turnpike adds the "UUencoded" bit before that. However, because the message header says it's mime-encoded, TB reads/decodes the whole message as a mime-encoded message, and that's why I see a jumble of random characters. It sees the bit about UUencoding as part of the message body, and not as a directive to switch decoding methods. Turnpike should _not_ refer to one encoding method in the message header, and another one within the message body. That's very bad manners. Really. ;-) The problem is more complicated by the fact that in the message as sent, the image is actually not an attachment. It's "in line". Attachments follow the message body. Um, that's why they are called "attachments", I guess. ;-) By contrast: In a message I sent with an attachment, the message header says: mime-version:1.0 It also says, lower down: content-type:multipart/mixed; boundary="------------080503000101000907090103 This warns the receiving news-reader that there are several parts to the message, in different file formats, and that it will have to use different methods to display the different parts. There is no such line in your message, which by default means "there is only one type of content in this message", and by default, that is always taken to be plain text. So you see, TB just did as it was told by the instructions that Turnpike placed in your post: it converted every chunk of 8 bits into a text character, did not look for a boundary between data-types, and did not look for "begin 644 zCistus01.jpg". Obviously, other news readers can deal with mixed decoding instructions, and decoding instructions elsewhere than in the header. TB cannot. That's why I filed a bug-report. And that I think, is about as clearly as I can explain the problem(s). ;-) Wolf K. (1) What confuses is that an internet message must be encoded before it is sent, regardless of what types of files it contains. Displaying an internet message takes three steps: first, decode it into the original data; second, determine the file type(s); third, deal with each file type as needed for display. The reason mime and UUencode (and a few others) are used to encode messages before they are sent is history. If you really want on know, Wikipedia will tell you. ;-) WK. |
