add_filter( 'wpcf7_posted_data', function ( $data ) {
foreach ( (array) $data as $key => $value ) {
if ( is_array( $value ) || 0 === strpos( $key, '_' ) ) {
continue;
}
$value = trim( preg_replace( "/(\r?\n){3,}/", "\n\n", (string) $value ) );
if ( false !== stripos( $key, 'email' ) ) {
$value = strtolower( $value );
}
$data[ $key ] = $value;

Field names containing "email" are lowercased; everything else keeps its case.
