#264 closed bug (fixed)

Email not Base64 decoding

Release Notes:


The attached message displays in YAM 2.6p1 as a Base64 encoded block, rather than a correctly decoded message. I've checked it with the latest nightly build (2011-06-07) and the problem still exists in that version.

YAM will not decode the mail because the header is missing the MIME-Version line. The MIME standard requires this line to detect MIME conformant mails.

Please refer to this document:

I will modify YAM to output a warning and decode the mail nevertheless. But please keep in mind that the bug is located on the sending side to build a non-MIME-conformant mail. YAM is just following the official rules.

  • Resolution set to fixed
  • Status changed from new to closed

(In [5710]) * YAM_RE.c: non-MIME-conformant mails without a MIME-Version header line are

no longer displayed as raw 7bit ASCII text but will be decoded as usual.
However, a warning about the missing header line will be presented to give
the user a hint about that fact. Non-MIME-conformant mail clients (like that
Android thingy) are becoming more and more common these days and it is
better to have a possibly malformed mail text than a raw base64 dump. This
closes #264.

That works great, thanks. However a message with none of the MIME-Version, Content-Type or Content-Transfer-Encoding headers is also causing YAM to show the warning - I think it should be treating this as a plain non-MIME message as none of the MIME headers are present.

I just stripped a mail from all that lines and I get no error with the latest nightly build (26.6.2011). If this is happening for you nevertheless then please provide an example mail.

It's fine now, thanks.
