Workaround for quoted printable encoding of attachments

Workaround for quoted printable encoding of attachments

[Rene H. Larsen]

If you, like me, have problems with binary attachments in pGnus being
encoded as quoted printable instead of in base64, this may help you.

Just insert this into your .gnus:

(defun mm-qp-or-base64 () 'base64)

This will effectively disable pGnus' (apparently broken) heuristics to
determine whether a file is binary, and always choose base64
encoding. Unfortunately, "text/*" attachments will then also be base64
encoded. On the other hand, "message/rfc822" attachments are
unaffected.

This does not fix the underlying problem, but should merely be
regarded as a workaround.

HTH.

I guess your solution is not appropriate. Why not try the following
code in your .gnus?

(setq mm-content-transfer-encoding-defaults
  '(("text/x-patch" 8bit)
    ("text/.*" qp-or-base64)
    ("message/rfc822" 8bit)
    ("application/emacs-lisp" 8bit)
    ("application/x-patch" 8bit)
    (".*" base64)))

This is much nicer, thanks.  My workaround was just a desperate try at 
solving an immediate problem.

Why is something like this not the default, by the way?  It doesn't
make sense to QP encode most binary formats since newlines might be
screwed up at the receiving end.

I guess it is for shorter encoded message.

Have you tried one of my patches sent a few days ago? That will fix
bug of broken QP encoded message by folding long lines. I am not sure
whether you got the same bug.
