I want messages to go to a ‘spam’ folder
In most cases, you will also want anything flagged as spam to be automatically moved to a spam/junk folder.
To enable this behaviour:
1. Navigate to the ‘Spam Filters‘ tool
2. Next to ‘Move New Spam to a Separate Folder (Spam Box):‘ Toggle the switch to the ON position (the toggle switch will appear blue if enabled and grey if disabled).

To adjust the sensitivity of the spam filter
PLEASE NOTE: Changing the “Spam Threshold Score” will affect how aggressive or relaxed the spam filtering is. Setting a lower score will mean a more aggressive filter, likely resulting in many incorrectly flagged messages. A higher score will be more relaxed and only flag mail that is very obviously spam.
- e.g. A threshold score set to 10 will only mark messages that are very obviously spam.
- e.g. A threshold score of 2 will label many messages as spam, including messages that are likely not spam.
- We recommend that users start with the default setting of 5 and make small, incremental adjustments if needed.
