hey Joe,
I was attempting to solve the missing X-spam headers by stopping and restarting spam and virus filtering from the Features and Plugins page.
After I'd unchecked those features it took me to the System Information page and showed a button to restart the Clamd server, which I did not check.
I went back to the Features and Plugins page and checked spam and virus scanning and got the message "Failed to save enabled features : You have selected to use clamdscan for virus scanning, but the clamd server it talks to is not running"
So I went back to the System Information page and the button to start Clamdserver was missing.
Is this a bug? How do I start the clamd server?
Help on getting the X-spam filters working reliably would be very much appreciated.
