Hi,
I'm trying to set up SPX encryption but can't get it to work. This is what I have done:
- Created an SMTP profile and punting a particular domain's emails through the profile.(That domain is external to our system.)
- Turned on SPX encryption and created an SPX template. Linked the SMTP profile to the template.
- Run the Sophos Outlook Addin on a test PC.
When I create and attempt to encrypt an email the x-sophos-spx-encrypt header is being added, the correct profile is being used but the message is not encrypted. The only difference the receiver sees is the header and "Please treat this as Confidential" when viewing the message in Outlook. I've also tried using the [secure:password] format in the subject.
Any ideas?
It's very worrying that the x-sophos-spx-encrypt header has been added but UTM sends the message in the clear. Even if the system is not configured for SPX, the header should surely prompt UTM to quarantine the message or return is to the sender? It's unacceptable that the user asks for the email to be encrypted and it is sent cleartext.
