One tends to forget what is not 'in your face'.

'Sovereign Governments' - US, UK, EC as well as PRC, have
legitimate concerns about cross-border communications - and have
had absolute power to monitor and control them since 4WPM cables
were the 'bleeding edge'. 'Court Orders' not required.

Politics aside, one simply cannot expect to run an MTA without
'true' fixed-IP, DNS and PTR records any longer.

Fewer and fewer MTA will accept such connections, let alone the
traffic, and 'EasyDNS' operators are often blacklisted along
with dynamic IP blocks.

PRC rules are usually promulgated 'top-down', with local cadres
or commercial service providers expected to handle the 'last
mile' of compliance. Few are where you can read them yourself.

Your connectivity ISP is almost certainly duty-bound to tell you
to just *stop it*, lest their own license is imperiled.

BTW - that is not just PRC.

*MOST* connectivity ISP worldwide ban MTA or website serving
that is not part of the 'virtual' package they issue to a
subscriber.

Get your ToS out, and have it translated if need be.

At least Mandarin is easier to understand, cheaper to translate,
and more consistent than US 'legalese', which hides stuff in
'plain view'.
