blacklisting Feedback Suggestion for Mozilla Thunderbird

[SirMadCatter]

**Feedback Suggestion for Mozilla Thunderbird:**

Mozilla Thunderbird currently lacks a direct **email blocking (blacklist) feature** for specific addresses or domains. Users must manually create message filters to delete or junk messages from unwanted senders, which is less intuitive and efficient.

**Suggested Improvements:**

1. **Implement a Dedicated Block List:** Add a user-friendly "Block Sender" option (e.g., via right-click on a message) that automatically adds the sender's address to a centralized blacklist. Emails from blacklisted addresses should be automatically deleted or moved to Junk/Trash upon arrival.

2. **Automate Blacklist Population from Filters:** Enhance the message filter system by allowing filters to automatically add matching addresses to the block list. For example:
* If a message is **manually marked as Junk**, provide an option to "Add sender to Block List."
* Allow filters to include an action like "Add sender to Block List" when conditions are met (e.g., email is tagged with `JUNK` or `SPAM`, or has a high spam score).

This would streamline spam management, reduce manual filter creation, and bring Thunderbird's functionality in line with other modern email clients.
