However, I think 2821bis needs a little extra text to notify
operators that they may need to upgrade or reconfigure to comply
with 2821bis. For example bs.jck.com currently refuses mail from
AAAA-only addresses:
There's nothing wrong with that if the host is only IPv4 aware. The
IPv6-only sender would be connecting to the IPv6 relay for that
domain to send mail as follows:
MAIL FROM:<[EMAIL PROTECTED]>
250 OK
RCPT TO:<[EMAIL PROTECTED]>
250 Accepted
Exim users can comply by disabling the sender_verify variable,
postfix users can disable reject_unknown_sender_domain, I don't know
the relevant variable for any other MTAs.
That might cause more problem than it solves.
