None of which helps the OP. Thinking further about the possible
blacklisting of CGNAT IP addresses, don’t most mail providers now require
authentication, eg authenticated SMTP? So they know who their possible spam
originator is and can disable at account level. Disabling at IP address
level doesn’t seem sensible in the modern world. Gone are the days where
you could simply fire email at an unauthenticated SMTP server on port 25.
