Thunderbird FAQ

Delivery failure sending attachments

When using Thunderbird to send a .doc attachment the e-mail message is rejected by Exchange 2007 with the response:
#554 5.6.0 STOREDRV.Deliver;
Corrupt message content ##rfc822;.

In some instances the Thunderbird mail client may send a .doc file (Word attachment) with the incorrect mime-encoding of 'application/applefile'. Perform the following steps to resolve the problem:

  1. Close Thunderbird.
  2. Navigate to the following directory based upon your OS:
    • Windows 2000/XP:
      • C:\Documents and Settings\<your username>\Application Data\Thunderbird\Profiles
    • Windows 7:
      • C:\Users\<your username>\AppData\Roaming\Thunderbird\Profiles
  3. Open the directory named with a random set of characters, e.g. "yo6luyl8.default". There may be multiple directories if you have multiple Thunderbird profiles.
  4. Delete the file named 'mimeTypes.rdf'.
  5. Restart Thunderbird which will recreate a correct mimeTypes.rdf

Thunderbird seems to acquire this behaviour when it receives incorrect attachments sent by an email client on a Mac.

Can't Connect to staffmail/sms

The long awaited upgrade to staffmail requires some changes to be made to mail program settings. Please see the EUCS Documentation for suitable settings.

Fixing Certificate Problems in Thunderbird

  1. Download this file to your desktop: Ed Uni Master Cert
  2. Run thunderbird
  3. On Linux: Click on Edit->Preferences->Privacy->Security->View Certificates->Authorities
  4. On MS Windows: Click on Tools->Options->Privacy->Security->View Certificates->Authorities
  5. Scroll down the list and delete any ed.ac.uk certs, they might be listed as "The University of Edinburgh", it's in alphabetical order.
Now we'll install the ed.ac.uk cert from the same window.
  1. Click on "Import" in the Certificate Manager window that you opened above.
  2. Navigate to your desktop and select the file "eduni.pem" click "Open".
  3. A new window will open with three options. Select the top two and unselect the last. Click Ok, then click "OK" again to get out of the Certificate Manager.
  4. Close Thunderbird and then rerun it.
  5. At this stage you may remove the Ed Uni Master Cert (filename eduni.pem) from your desktop, it's no longer needed.

ThunderBird and Sent Mail

If your thunderbird program on Windows has stopped saving sent mail in the "Sent Items" folder and this behaviour continues no matter how many times you alter the settings then follow these instructions carefully.

  1. Close all Thundebird sessions, take care to check that they are all closed down.
  2. Right click on "Start" then select "Explore"
  3. Inside Explorer navigate to Desktop->"My Computer"->"Local Disk (C:)"->"Document and Settings"
  4. Select the folder with your login name then goto "Application Data"
  5. Rename (do not delete!) the "Thunderbird" folder. Keep Explorer open you'll need it later.
  6. Start up Thunderbird, it will ask you for several settings. If you're a member of staff the IMAP and SMTP settings are "imap.staffmail.ed.ac.uk" and "smtp.staffmail.ed.ac.uk" respectively.
  7. Once thunderbird has finished asking you questions close thunderbird.
  8. Go back to Explorer and you should see that there is a new "Thunderbird" folder. Buried inside the old Thunderbird folder is your old addressbook. The address book file is called "abook.mab" but it can be a little tricky to find it:
    • Look inside the "Profiles" in the old Thunderbird folder
    • There will be a folder that starts with several random characters and ends ".default". So it may look like "sdffrg.default" of "123abc.default".
    • Inside that folder is "abook.mab".
    • Copy the "abook.mab into the ".default" folder in the new Thunderbird folder.
  9. Now start Thunderbird. You may need to follow the instructions above "Fixing Certificate Problems in Thunderbird".
