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

  1. Make sure you have already created at least one e-mail account for your domain. If you have not done this, please see this article to learn how to create an e-mail account using cPanel.
  2. Start Thunderbird.
  3. On the Edit menu, click Account Settings. The Account Settings page appears:

  4. Click Account Actions, and then click Add Mail Account:

  5. In the Your full name text box, type the name that you want to appear on messages you send.
  6. In the Email address text box, type the e-mail address of the account that you created in cPanel.
  7. In the Password text box, type the password for the e-mail account that you created in cPanel.
  8. If you do not want to retype the account password every time you start Thunderbird, select the Remember password check box.
  9. 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 6.

    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 Configure manually. Remember that you should use SSL/TLS connections, with IMAP using port 993, POP3 using port 995, and SMTP using port 465.
  10. Click Done:

  11. Click Finish.
  12. To retrieve messages from the account immediately, click Get Messages. Thunderbird downloads the messages for the account.
