X-SmarterMail-SmartHostSpam value from header is being encoded in base64
Problem reported by Webio - 3/26/2023 at 8:24 AM

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:

Hello, 

Thanks for reaching out regarding this issue. 
8454 was released on 2/23/2023. Did this issue occur with Build 8482?
If not can you upgrade to Build 8482 and test it again?
You can download that via the following link.

Looking forward to hearing from you. 

Thanks,

Yes. This issue occured on 8482 build. I'm not sure about previous builds between those two since I upgraded from 8454 to 8482.
