How to configure Mozilla Thunderbird

  1. Start with the New Account Wizard.
    The first time you launch Thunderbird, the wizard comes up
    automatically. On subsequent launches, you can invoke the
    wizard manually from menubar: File,
    New, Account.
  2. Click on Next >.
  3. Enter your name and e-mail address.
    Then click on Next >.
  4. Select the IMAP option. Then fill out the
    Incoming Server field with imap.math.arizona.edu,
    and fill out the Outgoing Server field with
    smtp.math.arizona.edu.
    Click on Next >.


    Note:
    If you entered a name of an outgoing server in the past,
    then you will not be shown the Outgoing Server field,
    and instead the previously entered value will be used.

  5. Fill out the Incoming User Name and
    Outgoing User Name fields with your user name.
    Click on Next >.


    Note: If you entered an outgoing user name in the past,
    then you will not be shown the Outgoing User Name field,
    and instead the previously entered value will be used.

  6. Enter a name you would like to use to refer to this account.
  7. Click on Finish.
  8. Now go to “Account Settings”, which will be in either the Edit menu or the Tools menu (depends on your operating system).
    In the Account Settings dialog that will appear, on the left click on
    “Outgoing Server”. Then, on the right-hand side, click the
    “Edit” button.
  9. In the SMTP Server dialog that appears, change the port number to 587,
    enable secure authentication using your own network account username,
    and choose “TLS” as the secure connection type.
  10. Back in the Account Settings dialog, on the top left click on “Server Settings”. Then, on the right-hand side,
    if the security choices offer both “TLS” and “SSL”, then choose “TLS”. (Otherwise, you're probably running an older version of Thunderbird, so look for a checkbox titled “Use secure connection (SSL)”, and check that.)
  11. Quit and restart Thunderbird.
