[WARNING: MESSAGE ENCRYPTED] not visible in the message tracking

[Densha Otoko]

For example, in the outbound mail policy in GUI, [WARNING: MESSAGE ENCRYPTED] is added to the subject by the antivirus.

When searching for '[WARNING: MESSAGE ENCRYPTED]' in the message tracking I only can see logs like:

'scanned by Anti-Virus engine Sophos. Interim verdict: ENCRYPTED'

But there are no logs indicating that '[WARNING: MESSAGE ENCRYPTED]' was added in the message tracking logs

Is it a specification that it is definitely added to the beginning of the subject when sending despite there is no [WARNING: MESSAGE ENCRYPTED] logs found in message tracking ?

Also, is there a way to confirm in the logs that it is added to the beginning of the subject?

Thank you

The prepend is set/enabled under Mail Policies/Incoming Mail Policies, in the policies that have antivirus enabled.  Its part of the antivirus settings.

The fact that Sophos marked it Encrypted is the log entry.
