Both the message and the file is showed.. The problem is more visible when using more avanced css layouts. Text in the attachment gets printed above the mail text etc. If the attachment is marked with Content-Disposition: attachment the attached html file should not be show. If it is marked with Content-Disposition: inline it should though. I found this to be an error, or do have I misunderstood the meaning of Content-Disposition. Reproducible: Always Steps to Reproduce: 1. Create a e-mail in HTML format 2. Attach a HTML file with an advance css layout (with position: absolute) 3. Send it to yourself Actual Results: Watch the e-mail.. The attachmend get printed on top of the email text Expected Results: The attachment should not be showed. This only occurs if the mime type of the attachment is text/html, if it is marked as application/octet-stream it will work as expected.

I don't think this is a duplicate of the bug in question. I was un-aware of that bug. Originally this bug occured when using a sendmail script in php where I marked all attachments as 'Content-Disposition: attachment'. And before trying I though that Thunderbird also sent the attached file as 'Content-Disposition: attachment' when attaching a html file.. That was not the case as shown by bug 65794. This bug is not about setting the wrong Content-Disposition when sending but doing the wrong thing with Content-Disposition when it reads a message. Perhaps they are both linked to each other but I don't think it is the same bug. This occurs when reading a mail. The other bug is while sending a mail.
