Message aging
From MozillaZine Knowledge Base
Look for message aging (with permanent deletion) in Thunderbird 1.5. In nightly builds, which are for testing and not recommended for general use, settings are currently available at:
- "Tools -> Account Settings -> [account name]" and then "Disk Space" (for Local Folders and POP accounts) or "Offline & Disk Space" (for IMAP accounts).
- "Edit -> Folder Properties... -> Retention Policy" (for folder-specific settings).
Automatic deletion appears to occur only when a folder is opened.
