IIRC, header_checks see only raw headers, so anything encoded with RFC 2047
syntax might look nothing like that. For example, 2047 base-64 encoded
headers seem popular in spam, and those could contain 'casino' without,
y'know, containing 'casino'.

I suggest you use something like amavisd-new which pushes the email through
all the relevant normalization before it applies rules like that.
