Certain attachment MIME structure is not recognized by Mozilla
** Observed with 11/18/99 Win32 M12 build ** This bug was originally reported by Henrik Gemal <firstname.lastname@example.org>. Outlook 2000 uses a type of MIME structure like the following when the user attaches a file without bothering to write a message into the message body. =================== From: Henrik Gemal <email@example.com> To: "'firstname.lastname@example.org'" <email@example.com>, "'firstname.lastname@example.org'" <email@example.com> Subject: Body=GIF Date: Mon, 22 Nov 1999 11:30:49 +0100 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2232.9) Content-Type: image/gif; name="title.gif" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="title.gif" Content-Location: ATT-0-E5CE1DC335A0D311A75500104B7915CA-T ITLE.GIF (B64'ed data follow) .... =================== Mozilla is not able to display an attachment clip in the Viewing window. Note the "Content-Disposition: attachment;" line. This should be enough to have it recognized as an attachment. Right now, Mozilla simply shows blank body with no "clip" icon. Thus, there is no way to know that there is an attachment here. Under 4.7, the attachment link and icon are displayed for this message. Contrast this wirh a message generated by Outlook Express 5: ========================================= Content-Type: multipart/mixed; boundary="----=_NextPart_000_000A_01BF3487.20EC9C70" X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2314.1300 X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 This is a multi-part message in MIME format. ------=_NextPart_000_000A_01BF3487.20EC9C70 Content-Type: text/plain; charset="iso-2022-jp" Content-Transfer-Encoding: 7bit ------=_NextPart_000_000A_01BF3487.20EC9C70 Content-Type: application/octet-stream; name="ws_ftp.log" Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="ws_ftp.log" (file omitted) ========================================= Here, there is an empty body but with a structure. Mozilla is able to pick up the structure and create a clip icon. The body display is simply empty. Under 4.x, we show a little table with the name of an attachment for a message of this type. I gather we already have a bug for this part, i.e. not creating some display in the Viewing window. Assuming this to be the case, we should use this bug for not showing the clip icon or not recognizing the first type of attachment structure mentioned above.
The aboev attachment contains 2 messages: 1. A msg sent from Outlook 2000 whose attachment is not sensed by Mozilla. (discussed above) 2. A msg sent from Outlook Express 5 which contains an empty MIME structure followed by an attachment structure. Mozilla does sense there is an attachment here and displays an icon. I made an error in MIME type for ZIP. Please save "showattachment.cgi" as "showattachment.zip".
Ok, there is really only one bug here...the first message with the attachment/gif as a body is being displayed incorrectly. I need to look into that issue. The second message that has a logfile as the attachment is being displayed correctly. 5.0 will no longer show that table with cryptic information in the message body for attachments. The pulldown menu is the place to look for any and all attachments. - rhp
