Exim has a hard limit of 2048 on the size of a DNS response (unless the OS defines a bigger limit, but most OSs set it at 512) so it's going to drop parts of a very large MX RRset anyway. I don't think this is really worth worrying about. However, to be safe, all the dn_expand calls need to be checked for overflow (how annoying) so the patch isn't quite complete.
