You mean like this standard rule from SA 2.50 and higher?
header FROM_NO_LOWER From !~ /[a-z]/ describe FROM_NO_LOWER 'From' has no lower-case characters
Whoops.. my bad, that looks for a no-lower email address..
Let's instead look at a rule from sa 2.30 through sa 2.44:
header ALL_CAPS_HEADER ALL =~ /\n(?:TO|FROM|SUBJECT|DATE):/s
