Affected Version: SFOS 20.0.2 MR-2-Build378
When creating a new SMTP route & scan policy in Protect > E-Mail > Policies & exceptions you are unable to enable "Reject based on RBL".
When you already have an existing SMTP Route & scan policy with "Reject based on RBL" enabled, you'll experience the same problem after unchecking that option.
This appears to be a problem with the most recent version of Sophos Firewall. Can anyone confirm this please?
