Can KSS forward syslog messages "as-is" (with proper options checked)?

Objective: Forward syslog messages from McAfee ePO to QRadar.

New Facility: No change

New Level: No change

Send with RFC3164 header information: Unchecked

Retain the original source address of the message: Checked

Spoof Network Packet: Checked

Issue: QRadar admin claims syslog messages relayed from McAfee ePO are not parsing correctly--implying that KSS is somehow mangling the messages. True?

McAfee ePO DSM is installed on QRadar.
