Hello Alexey,

Note that this was about Frontdoor - or any other classic POTS mailer - with a vmodem or telnet shim.

All very well, but both Frontdoor the Vmodem and Telnet shims are abandonware and know nothing about IPv6 and they probably never will.

To stop that non IPv6 aware abandonware from attempting to call an IPv6 only node, a nodelist flag is needed.

New IPv6 aware suff can do it better.
