The actual reported problem does not in fact require a client MTA to have a PTR record for its IP address, all that the client needs to do is send a HELO name that resembles an FQDN. Mind you an MTA that lacks a PTR for its IP address will be reject by pretty much every peer MTA on the Internet. The ietf.org lists would be the least of its problems. Given that said PTR is published, its target may as well be the HELO name, there's no reason to take a principled stand on one's moral right to use an address literal, we have more important issues to consider. Over and out. -- Viktor.
