Over deze add-on
Get notified when your mailbox is almost full (quota warning).
Many mail providers, especially free ones, do not make server-side quota information available. Because of this, Thunderbird cannot determine how much space is left on the server. This add-on addresses the issue by letting you manually define a quota per account. It then compares this limit with the actual disk space used by the account locally.
Note: This add-on works best with IMAP accounts, where the local mailbox storage usually reflects the actual content on the server.
Features:
- Per-account quota warning
- Toolbar icon with badge
- Options page with details & manual check
- Configurable auto-check interval
- Multi-language support
