RFC problems ...

[Yann Bachy]

Hi

thanks for your help but I kind of solved the problem in the  
mean-time... I'll explain you what I did:

I activated the brokenrfc2231 option to get the following header:

--=_2qw5ii3ew2uo
Content-Type: application/vnd.oasis.opendocument.spreadsheet;
  name="=?utf-8?b?dMOpdMOpw6Aub2Rz?=";
  name*="utf-8''t%C3%A9t%C3%A9%C3%A0.ods"
Content-Disposition: attachment;
  filename="=?utf-8?b?dMOpdMOpw6Aub2Rz?=";
  filename*="utf-8''t%C3%A9t%C3%A9%C3%A0.ods"
Content-Transfer-Encoding: base64


then I changed the following file:

/var/www/horde/lib/Horde/MIME/Part.php


at the following block:

/* Add any disposition parameter information, if available. */
             if (!empty($name)) {
                 $encode_2231 = MIME::encodeRFC2231('filename', $name,  
$charset);
                 /* Same broken RFC 2231 workaround as above. */
                 if (!empty($GLOBALS['conf']['mailformat']['brokenrfc2231']) &&
                     (strpos($encode_2231, '*=') !== false)) {
                     $disp .= '; filename="' . MIME::encode($name,  
$charset) . '"';
                 }
                #$disp .= '; ' . $encode_2231;
             }




I commented out the following line:
                #$disp .= '; ' . $encode_2231;


So I get a header that looks like the following:

--=_mjzeikmmlhk
Content-Type: application/vnd.oasis.opendocument.spreadsheet;
name="=?utf-8?b?dMOpdMOpw6Aub2Rz?=";
name*="utf-8''t%C3%A9t%C3%A9%C3%A0.ods"
Content-Disposition: attachment;
filename="=?utf-8?b?dMOpdMOpw6Aub2Rz?="
Content-Transfer-Encoding: base64


now outlook will correctly read the filename, and mailscanner accepts  
to check the message...


Don't hesitat if you've got any further questions... or comments ;)

thanks anyway!
