Implementation

List<MailAddress> decodeSender({bool combine = false}) {
  var replyTo = decodeHeaderMailAddressValue('reply-to') ?? <MailAddress>[];
  if (combine || (replyTo.isEmpty)) {
    final senderValue =
        decodeHeaderMailAddressValue('sender') ?? <MailAddress>[];
    if (combine) {
      replyTo.addAll(senderValue);
    } else {
      replyTo = senderValue;
    }
  }
  if (combine || replyTo.isEmpty) {
    final fromValue = decodeHeaderMailAddressValue('from') ?? <MailAddress>[];
    if (combine) {
      replyTo.addAll(fromValue);
    } else {
      replyTo = fromValue;
    }
  }
  return replyTo;
