Spam, blocked senders and quarantine

Everything is in Settings, Spam & blocked senders.

• Sensitivity: Strict catches more but can misfile real mail. Relaxed lets more through. Balanced suits most people.
• Always allow and Blocked senders accept a full address ([email protected]) or a whole domain (example.com).
• Quarantine holds the most suspicious messages instead of delivering them. You can release one if it was a mistake. Messages with viruses cannot be released.
• Quarantine summary email sends you a regular list of what was held back.

In a message, Report spam moves it to Spam and helps the filter learn. Not spam puts it back.
