I forgot to mention that the instructions I found on the Mozilla support page (https://support.mozillamessaging.com/en-US/kb/manual-account-configuration) do not work, but I think I just figured it out, after trying for two days.
Open the Account Settings dialog Select Add Mail Account under the Account Actions option list Enter the relevant information and click on Continue As soon as the "Looking up configuration..." message appears, click the Manual Config button. This stops the automatic set up and drops you to a screen that allows you to configure the parameters manually. Click the Create Account button. Sorry to bother everyone with this. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
