Tele-Support HelpDesk Hot Tips

Tech Tip:

When .txt or .html attachments are sent to my HelpDesk e-mail through Mozilla Thunderbird, they are stripped from the e-mail upon arrival.

This is a bug in Thunderbird, which assigns a content disposition of "inline" to .txt and .htm attachments, which is a violation of current e-mail standards. You can review bug details as written up in Mozilla's knowledge base.

To resolve this issue, the e-mail sender will have to take the following steps:

In Mozilla Thunderbird all versions:

Click on "Tools" -> "Options."

Select the "Advanced" panel and then the "General" tab.

Click on the "Config Editor" button.

Locate the "mail.content_disposition_type" preference and set its value to "1".

Save any changes and then re-send the e-mail with attachments, which should now show up as proper attachments rather than inline attachments.

In earlier versions of Mozilla Thunderbird (pre-1.0.5):

Browse to your Mozilla user profile folder and edit the file called "user.js".

Insert the following line into the user.js file:

      user_pref("mail.content_disposition_type", 1);

Save these changes.
