Header parsing, again.

I saw this topic addressed earlier, but it seemed to peter out with no resolution... I'm using an AppleScript in Mac OS X's Mail.app to report to SpamCop, enclosing full header and content. More often than not, SpamCop chokes on the headers, and refuses to parse the body of the message for links.

I've sent one of my reports to myself, and here's the header section...

As received by me, the first and third Received: headers are unbroken. The second is broken (as it was when it arrived), with the second line indented -- by a single space, but indented. The Content-Type: header is deeply indented. All other headers are reasonably short. Then comes a blank line, and the content.

The mail agent responsible for the single-space indent, by the way, is qmail.

On the face of it, this complies with the explanation given for the error. The message is, as far as I can tell, in the original format, and header breaks are escaped with indentations. Maybe the scri_pt has an off-by-one on the indent detection?

Or have I missed something?

Can you confirm that there are still no breaks in the long header lines when you submit them to SpamCop, perhaps by forwarding to yourself like you forward to your submit address?

The space or tab as the first character of a line is a standards-compliant method of indicating that the line is a continuation of the previous line.

The original message in this thread included just such a header. Here is another, forwarded to myself, and rejected for content-scanning by SpamCop as bad. I also include the first two lines of the body of the spam:

Note that in this case, there aren't even any particularly long lines to wrap.

All I can say is that I copied your last example, pasted it into the web-form, and it parsed through with no errors. On the other hand, manipulating your first example to include the missing components (bit of a body, boundary lines, etc.) and it parsed also. So there appears to be something that gets "corrected" in your copy and paste as compared to what's actually getting submitted. Not a lot of help I know, it's just that I can't seem to recreate your "problem" using your examples ..??

I tried pasting the body of my report, as mailed to myself, into the web-submission form. It parsed cleanly. There's no opportunity for cleanup in this process: Click at start-of-body, shift-click at end-of-message, copy, switch from Mail to Safari, select the submission form, paste.

I think I've shown that the reports are leaving my mailbox in the proper format -- a mailed copy looks right, and the mailed content parses when presented directly to the scri_pt. Somewhere after my mailing and before the scri_pt, my reports are getting munged. Is there a way to pin this down better, or will I just have to live with body-link reporting being broken most of the time?

Near as I can tell, I'm not doing anything wrong. If you have any other suggestions, I'd be glad to hear them.
