X-SmarterMail-SmartHostSpam value from header is being encoded in base64

Hello,

it looks like after updating my incoming gateways to release candidate (which are passing messages to non beta version of SmarterMail) header entry X-SmarterMail-SmartHostSpam content is being passed as base64 which is making (EDIT: anti) spam unusable on main SmarterMail instance (gateways are passing SPAM score to main SmarterMail server and there is being SPAM logic being done).

Example:

X-SmarterMail-SmartHostSpam: 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

If you run base64 decoding on this string you will see:
