Security Settings

    • None: The connection is not encrypted.
    • SSL/TLS: (Recommended when possible) The connection is encrypted.
    • STARTTLS: The connection starts as unencrypted, but attempts to make a secure connection if the server supports it.

Server Settings

  • Check for new messages at startup: With this setting enabled, Thunderbird will check the account for new message when you start Thunderbird.
  • Check for new messages every __ minutes: Make Thunderbird check for new messages automatically on a set time interval.
  • Allow immediate server notifications when new messages arrive: (IMAP accounts only) With this setting, Thunderbird will use the IMAP IDLE command, allowing you to receive new messages as soon as they arrive on the server without having to check the server for new messages.

When I delete a message: (IMAP accounts only) By default, when you delete a message, Thunderbird will move it to the Trash folder for that account. Here, you can change that behavior.

  • Move it to this folder: Instead of moving the message to the trash folder, use this menu to select a different folder where messages will be moved to.
  • Just mark it as deleted: Using this setting will keep the deleted message in the original folder, but strike a line through it to show you it has been marked as deleted. To clear the folder of deleted messages, right-click on the folder and select Compact.
  • Remove it immediately: Choose this setting to make Thunderbird remove messages when you delete them, without moving them to any folder.
  • Automatically download new messages: (POP accounts only) If Thunderbird checks for new messages using the Check for new messages every setting and detects new messages, you will still need to click Get Messages to download those new messages. Enable this setting to automatically download those new messages when new messages are detected.

  • Empty Trash on Exit: With this setting enabled, Thunderbird will empty your trash folder when you exit the program/application.
  • Message Store Type: This setting determines if Thunderbird stores mail folders locally in single files (For example, there's a file called Inbox) or stores each message in its own file. For more information, see Maildir in Thunderbird.
    NOTE: This setting is determined when creating an account.
  • Local Directory: This is the location where Thunderbird stores messages for the account. If you'd like to store messages for the account in a separate location from the rest of your Thunderbird profile, click Browse to select the directory you want.

Advanced IMAP Settings

Security panel

tb52-accountsettings-security-win10 tb52-accountsettings-security-mac

Digital Signing

When you digitally sign a message, you embed information in the message that validates your identity. This is accomplished by using a digital certificate to sign your messages. For more information, see Digitally Signing and Encrypting Messages.

  • Digitally sign messages (by default): Enable this setting to make Thunderbird automatically sign your messages using the certificate selected above. If this setting is not enabled, you can sign a message in the composition window by going to the Options menu and selecting Digitally Sign This Message.

Encryption

When you encrypt a message, it appears to be "scrambled" and can only by read by a person who has the key to decrypting the message. This is also accomplished by using a digital certificate. For more information, see Digitally Signing and Encrypting Messages.

Default encryption setting when sending messages:

  • Never (do not use encryption): Set this preference to only encrypt messages that you choose when composing the message. You can encrypt a message in the composition window by going to the Options menu and selecting Encrypt This Message.
  • Required (can't send messages unless all recipients have certificates): Set this preference if you want all messages being sent to be encrypted.
