If you really think that rejecting email from senders that want to optimize their costs is a good strategy.... Well, IPv6 is simply a way to make email sending cheaper. So not supporting Ipv6 is an effective way to dump cheap sending. I guess anyone with a good corpus can easily check that "inexpensive ESP" are not more spammy than "fortune 500 ESP". Someone proposed to simply add some cost to every SMTP transaction as a way to stop the spam, some blacklist offer paid unlisting services, too... but spammers sometimes have more money to send email than the average user IMHO.
