You can adjust how sensitive the filter is by using the scale below. A setting in the middle is usually sufficient.
When the filter identifies a message as spam, it makes a report of all tests and scores assigned.
Include report in headers of original message
Include original as MIME attachment to report (Default)
Include original as text-only attachment to report
Use abbreviated report
The filter may add certain headers to your messages. You can control this behavior here.
Add headers to non-spam messages
Allow multiple lines in headers
Use "Spam Level" header
Spam Level Character:
When a message is identified as spam, the filter can append some text to the subject of the message.
Tag Subject lines
with this text:
Select all the languages you expect to receive e-mail in. Any messages received that are written in languages not checked will be considered possible spam in a foreign language.
Some checks use internet-based databases to identify spam. Check the ones you want to use.
