These additional filtering rules are based on common spammer methods and can reduce porn and other spam.

Emails in foreign character sets can also be blocked.

"Aggressive" options are not recommended, but may be suitable for small or family domains that want to block porn from minors. They will, however, block some legitimate emails and should therefore be reviewed regularly.

To change the Additional Filtering:

1. Click on "Edit" next to "Additional Filtering".
2. Check the boxes next to the filters you would like to enable, or uncheck to disable.
3. Select one of the four radio button options next to the action you would like to take on email caught with this filter.
4. Click on "Set" to save the changes.
