Description

[Jacob]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)
Build Identifier: 1.5.0.13 (20070824)

If embedded email attachment (Content-type: message/rfc822) is encoded with base64 (Content-Transfer-Encoding: base64), then embedded attachment is shown empty.


Reproducible: Always

Steps to Reproduce:
1. The script "base64-embed" is included below.
Use perl script "base64-embed" to generate and send test message.
Send test message once fro Firefox, once to Outlook as folows:
     perl base64-embed Sender@Domain Recepient@Domain SMTP-SERVER
2. In Firebox, receive the message and double-clock on the attachment.
3. Observe that attachment looks empty in Firefox, subject is empty.
4. Observe that raw message is apparenty rfc-complaint and that Outlook
shows the attachment properly if you double-clock on the atachment.
In order to see the contents of the message sent, do:
     perl base64-embed Sender@Domain Recepient@Domain -


Actual Results:  
Attachment looks empty in Firefox, subject is empty.
The message appears to be RFC-compliant.
In Outlook, attachment is shown correctly.


Expected Results:  
That base-64-encoded email attachment be displayed correctly in Firefox.
