Mailbox: blocking and auto-filing

Blocked users

Someone you block can't message you, and you can't message them. Block by entering their exact username or email. You can unblock them from the same page at any time.

Auto-filing rules

A rule files incoming mail into a folder as it arrives. Match on a sender or on a keyword in the subject. Every message and every notification is its own item, so a rule applies to each one.

If you move an item by hand, later items with the same subject follow your choice rather than the rule. That keeps a recurring notification where you last put it.
