If the spammassassin header is like

email-header-n: foo
email-header-m: bar
 
X-Spam-Report: bar

Does that form follow rfc 5322?

If it does then any email header could have that
form and the header wrapping test should be
updated from

		if ($in_header_lines && $realfile =~ /^$/ &&
		    !($rawline =~ /^\s+\S/ ||
		      $rawline =~ /^(commit\b|from\b|[\w-]+:).*$/i)) {
			$in_header_lines = 0;
			$in_commit_log = 1;
			$has_commit_log = 1;
		}

to something like

		if ($in_header_lines && $realfile =~ /^$/ &&
		    !($rawline =~ /^ (?:\s*\S|$)/ ||
		      $rawline =~ /^(commit\b|from\b|[\w-]+:).*$/i)) {
