Setting up Mozilla Thunderbird

To configure Mozilla Thunderbird to work with your A2 Hosting e-mail account, follow these steps:

  1. Start Thunderbird.
  2. On the Tools menu, click Account Settings. The Account Settings dialog box appears.
  3. Click Account Actions, and then click Add Mail Account. The Mail Account Setup dialog box appears.
  4. In the Your name text box, type the name that you want to appear on messages you send.
  5. In the Email address text box, type the e-mail address of the account that you created in cPanel.
  6. In the Password text box, type the password for the e-mail account that you created in cPanel.
  7. If you do not want to retype the account password every time you start Thunderbird, select the Remember password check box.
  8. Click Continue. Thunderbird automatically detects the mail server settings for the account. If Thunderbird is unable to detect the settings, make sure that you typed the correct e-mail address in step 5.
    By default, Thunderbird selects IMAP with SSL/TLS for the incoming mail server, and SMTP with SSL/TLS for the outgoing mail server. If you want to change any of these settings, click Manual config.
  9. Click Done. Thunderbird verifies the password that you provided in step 6.
  10. To close the Account Settings dialog box, click OK.
  11. To retrieve messages from the account immediately, click Get Mail. Thunderbird downloads the messages for the account.
