How do I convert from Eudora to Thunderbird?

Thunderbird 3 and Eudora OSE (Penelope Eudora)

The ACCC supports Mozilla's Firefox browser and asks that everyone use it whenever they can instead of Internet Explorer, so it only seems reasonable that we include instructions on how to set up the Thunderbird email client to use Thunderbird is the email client that goes with Firefox. It's easy to use and quite reasonable. A lot like Firefox, in that way. If you're in search of a new email program, check Thunderbird out. It's nice. (And it does RSS.)

You can download Thunderbird at:

If you are converting from Eudora to Thunderbird, you might want to use Eudora Mailbox Cleaner 4.7.3 to convert your Eudora mailboxes (Mac OS or Windows) and Eudora Address Book to Thunderbird format. It can even take attachments from Eudora's 'Attachment Folder' and put them back in the message they came in for incoming email.

One thing you'll have to know when you're setting up Thunderbird is that, by default, you have to subscribe to mailboxes in order to use them. (Like Outlook.) To do this:

  1. Open the Subscribe dialog box:
    • In Windows, right-click on the name of a mailbox in the Folders panel and select Subscribe...
    • On Macs, Control-click on the name of a mailbox in the Folders panel and select Subscribe...
  2. Then highlight the names of the mailboxes you want to subscribe to and click Subscribe (or unsubscribe to and click Unsubscribe).
  3. Click OK.

Here is how you set up as the authenticated outgoing email server for Thunderbird.

Use port 587, which is set up exactly like port 25. You can also try 465.

  1. Open Thunderbird / Eudora 8.0.0b1.
  2. Select Tools, Account Settings... from the main menu.
  3. Click on Outgoing Server (SMTP) in the left area.
  4. Add. (Or Edit.)
    1. Description: whatever you want
    2. Server name:
    3. Port: 587
    4. Type the NetID that you want in the User Name: box. Thunderbird will ask you for the password the first time you send an email message.
    5. Click TLS, if available. (If you are using port 465 use SSL.)
  5. Click OK.
  6. If you have problems sending email, check to make sure your firewall is not blocking the port you used. (587, if you followed these instructions.)
