No X-Spam-Bayes header after I turn it on

[imlonghao]

What happened?

I have turned on Add Bayes score header to messages, but I can't find X-Spam-Bayes header in the eml.

The eml only has X-Spam-Result and X-Spam-Status

...
X-Spam-Result: DMARC_POLICY_ALLOW (-0.50),
	DKIM_ALLOW (-0.20),
	SPF_ALLOW (-0.20),
