• These instructions are intended specifically for setting up an email account in Mozilla Thunderbird 38.3.0 on Mac OS X 10.11.1.
• While the steps should be similar across platforms and operating systems, they may not necessarily apply to older versions of Thunderbird.
• For help with general email account settings, see How to Set up Any Email Client.

Step #1: Create the Account

1. From Thunderbird’s main screen, select Email under the Create a new account section, or use the main menu to pull down to File -> New -> Existing Mail Account.
2. On the window that pops up, select Skip this and use my existing email to proceed to the Mail Account Setup screen.
3. Here you will enter some basic information about the account:
   • Your name should be your name as you want it to appear in emails that you send.
   • Email address should simply be the email address you’re setting up.
   • Password is the email account’s password.
4. Select Continue. Thunderbird now will attempt to discover the settings for your account automatically. If autoconfigure is not successful, you will need to configure the account manually.

Step #2: Set Account Type

1. Select your account type, IMAP or POP3. For its ability to keep email in sync across multiple devices (desktop, laptop, phones and tablets), IMAP generally is recommended.
2. Now click on the Manual config button to expand the settings window and set your connection type.

Step #3: Set Connection Method

1. Fill out the Account Information fields using the instructions below as a guide.
2. Click Done to complete the setup process.
3. If you’re using standard (non-SSL) connection settings or are using secure (SSL) connection settings and have an SSL certificate installed on your mailserver, that’s all you’ll need to do set up the account. If you’re using SSL connection settings and are using the server’s self-signed SSL certificate, you will have one more step to complete.

Standard (non-SSL) settings

• Server hostname column: Enter your domain name (e.g., mail.yourdomainname.com or yourdomainname.com) on both the Incoming and Outgoing rows.
• Port column:
  • Incoming: For an IMAP connection, select “143”; For POP3, select “110”.
  • Outgoing: Select “25” or “587”
• SSL column: Select “STARTTLS” on both the Incoming and Outgoing rows.
• Authentication: This should be set to “Normal password” on both the Incoming and Outgoing rows.
• Username: Your full email address, not just the part before the “@” symbol, on both the Incoming and Outgoing rows.

Secure (SSL) Settings

• Server hostname column: Enter your server’s hostname (e.g., host.yourdomainname.com) on both the Incoming and Outgoing rows.
• Port column:
  • Incoming: For an IMAP connection, select “993”; For POP3, select “995”.
  • Outgoing (SMTP): Select “465”.
• SSL: This should be set to “SSL/TLS” for both the Incoming and Outgoing rows.
• Authentication: This should be set to “Normal password” on both the Incoming and Outgoing rows.
• Username: This is your full email address, not just the part before the “@” symbol, for both the Incoming and Outgoing rows.

Step #4: Security Certificate

1. If your server has a self-signed (free) SSL certificate installed on the mailserver and you attempt to make a secure connection using Thunderbird, you should see a warning in a popup window such as the one on the right.
2. If that is the case, you will need to click the Confirm Security Exception button to accept the certificate and complete the setup process.
3. If you choose, you also may check the box to Permanently store this exception so that you don’t need to continue to accept the certificate each time Thunderbird connects to your server.

You can edit an email account that already has been configured in Thunderbird, for example should you decide to switch between non-SSL and SSL settings or change the server’s connection port. You change the connection type between standard (non-SSL) and secure (SSL) by changing the hostname and port for the incoming and outgoing servers.

To avoid data loss, please use caution any time you change an email account’s connection type or delete an email account. Removing an email account from a mail client also will remove all messages associated with it on the device and, specifically in the case of POP accounts that are not configured to retain mail on the server, there may be no way to recover those messages. If you have any doubt or questions, please feel free to contact Heroic Support® for guidance.

Step #1: Edit Incoming Server Settings

1. To edit the incoming server, select your email address in the left pane and then click on View settings for this account in the main window.
2. In the account settings window, click on Server Settings to update the Server Name and Port.
   • Server Name
     • SSL settings will use the server’s hostname (e.g., host.yourdomainname.com)
     • Standard non-SSL settings will use the domain name (yourdomainname.com or mail.yourdomainname.com).
   • Port
     • SSL settings will use Port 993 for IMAP and Port 995 for POP3.
     • Standard non-SSL settings will use Port 143 for IMAP and Port 110 for POP3.

Step #2: Edit Outgoing Server Settings

1. To edit the outgoing server settings, click on Outgoing Server (SMTP) in the left pane, select your outgoing server and click the Edit button.
2. You can edit the server name and port in the popup window.
   • Server Name
     • SSL settings will use the server’s hostname (e.g., host.yourdomainname.com)
     • Standard non-SSL settings will use the domain name (yourdomainname.com or mail.yourdomainname.com).
   • Port
     • SSL settings will use Port 465.
     • Standard non-SSL settings will use Port 587 (depending on your server configuration, you may be able to use Port 25 as well).
3. Click on the OK button to save the outgoing server settings, then click on OK once more to exit the settings menu and begin using your email account with the new settings.
