Split attachments

[Jérôme Marant]

Hi,

  I'm using Oort Gnus 0.06, daily snapshot.
  I sent today a tarball to another personal address and Gnus proposed to
  split it, which I accepted.
  I received the mail in two parts : the first one coded in base64 and
  the second one coded in quoted printable. The problem is that none of
  both could be decoded by any MUA.
  Is it Gnus standard behaviour or it is a bug? If not a bug, what is
  the way to tune this?

  Thanks.

  Cheers,

Gnus never adds capital Quoted-Printable, so it is likely that some
MTA folds lines and adds the header.

According to RFC 2045, "the 76 character limit does not count the
trailing CRLF, but counts all other characters, including any equal
signs." So, the base64 text has 75 characters each lines should be
OK. But the MTA folds those lines. I think it is the problem.

This means the mail was too big. Gnus was affraid that the mail server
refused it,  so, it asked you to  split, and did so,  because you said
yes.

Here,  I suppose  you actually  forwarded a  mail, so,  these  are the
headers of the forwarded mail, not from yours.

So, this is effectively the second part of the message.

This part  is in quoted  printable. Probably the first  part contained
only   the    attachment   in   base64,   so,    with   no   non-ascii
characters. That's why is didn't have to get special encoding. 

This  one  also contains  the  end  of  your message,  with  non-ascii
characters, so, Gnus posted it in quoted printable.

This must be the same kind of problem as the one I had. See the thread
beginning by

<vpqr8ngfqbl.fsf@ubaye.imag.fr> (Problem with attachments.) 

I had difficulties  to open the attachment, but  actually, I could, by
just pressing `b', and waiting for a *long* time ... 

What I don't understand is why half quoted printable, and the other in
base64. 

The simplest solution is not to split the message.

It is not the behaviour Gnus is supposed to do.  But from your
description, I can not tell where the problem is.  Could you post the
headers of the messages?  It would be better to include a few lines of
the bodies too.

It is not the behaviour Gnus is supposed to do.  But from your
description, I can not tell where the problem is.  Could you post the
headers of the messages?  It would be better to include a few lines of
the bodies too.

Hi,

  I'm using Oort Gnus 0.06, daily snapshot.
  I sent today a tarball to another personal address and Gnus proposed to
  split it, which I accepted.
  I received the mail in two parts : the first one coded in base64 and
  the second one coded in quoted printable. The problem is that none of
  both could be decoded by any MUA.
  Is it Gnus standard behaviour or it is a bug? If not a bug, what is
  the way to tune this?

  Thanks.

  Cheers,
