Beginning with version 1.5, Thunderbird has a new message aging feature that can be used to automatically delete messages from folders based upon the age of messages or the number of messages in a given folder. It can be used with with e-mail, newsgroup, and RSS accounts. Be warned: messages deleted via this feature will be deleted permanently, not sent to the Trash folder. It is strongly recommended that you experiment with the message aging settings using non-critical messages (such as in an RSS account) before using the message aging feature with messages that you would not want to risk losing.

The automatic deletion of messages will take place when you open a folder. If you change your settings (as described below) with a folder already open, the changes will not be reflected in the currently open folder until you select another folder and then go back to the first folder.


Note: When using an IMAP account (with or without offline storage) or a POP account set to leave the messages on the server, the retention settings applies to both the local disk and the remote server copy, whether set for the entire account or specific folders.

Warning: The checkbox "Always delete read messages" does exactly what it says. Thus, even if you have "Don't delete any messages" selected in the main option, checking this box will delete a message once it is read (this box will be hidden by default in Thunderbird 3.0).


Account-specific settings

Message aging settings must be made separately for each mail or newsgroup account; RSS accounts use only folder-specific settings, described below. For mail accounts using the Global Inbox, you will set your preferences only for the account that shows in the folder pane (normally Local Folders). To activate message aging and set your preferences for a single account, go to:

  • "Tools -> Account Settings -> [account name]" and then "Disk Space" (for Local Folders and POP mail accounts) or "Offline & Disk Space" (for IMAP mail and newsgroup accounts).

Folder-specific settings

You can also make folder-specific settings for message aging. For example, if the account is set to the default "Don't delete any messages", you could choose to have a single folder set to delete messages older than 90 days old. You can access folder-specific settings in either of these ways:

  • Select a folder and then go to "Edit -> Folder Properties... -> Retention Policy".
  • Right-click on a folder and then select "Properties... -> Retention Policy".
