[TYPO3] direct_mail plaintext header sorting problems

[R. Germershausen]

hello list,

i have some problems with a plaintext utf-8 direct mail. settings are:

mod.web_modules.dmail.quick_mail_encoding=quoted-printable
mod.web_modules.dmail.direct_mail_encoding=quoted-printable
mod.web_modules.dmail.quick_mail_charset=utf-8
mod.web_modules.dmail.direct_mail_charset=utf-8

what happens is that sometimes it seems like the sort order of the parts 
is somehow wrong.
corexct mail looksl ike this:

X-OriginalArrivalTime: 04 Apr 2007 14:02:37.0930 (UTC) 
FILETIME=[E6FAA4A0:01C776C1]

------------part_1_4613af898c22a
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

------------part_1_4613af898c22a
Content-Type: application/octet-stream
  name="Attachment.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
  filename="Attachment.pdf"

wrong mail like this:

X-OriginalArrivalTime: 04 Apr 2007 14:02:37.0930 (UTC) 
FILETIME=[E6FAA4A0:01C776C1]

------------part_1_4613af898c22a
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

!!!this is the text which should be in the mail!!!


------------part_1_4613af898c22a
Content-Type: application/octet-stream
  name="Attachment.pdf"
Content-Transfer-Encoding: base64
