Header::read_attribute()split the attribute value into an array of single characters. A header value of a few megabytes that contains;and=(e.g. a long recipient list) allocated one array element per byte and exhausted a 512 MB memory limit while fetching the headers. The value is now walked by index, which keeps the parsing result the same and the memory flat.
