Yay.  Now we are getting somewhere... a problem to be solved :)

Let me first consider the problem for a bit.  I will come back to you 
after a think on this.  I am assuming you want this integrity check to 
pass when emailing Italian assets on Mars, or when assets on the Moon are 
emailing you, and mangling the payload so the user can't click $BADLINK is 
the issue.  How do these email systems interact with external entities 
email systems?  As normal?  What happens to the integrity check if you 
were to send an email to my MTA, which does not support it?

You are suggesting that "leaving the current TLDs implicitly on Earth by 
default," as defined below, alleviates this problem?

Fair enough.  You want end-to-end integrity, which means no mucking with 
the payload, as doing so will break (non?) standardized cryptographic 
additions to smtp which are required by law in one jurisdiction?  I would 
need to understand the mechanism used beyond "emails are signed" to make a 
full analysis, but I see the issue.

Again, fair enough.

Let me run this through the mental simulator, and see if this breaks any 
other parts.  I agree that keeping universal uniqueness of TLDs is useful. 
That said, while retaining the original TLDs to Earth use only, many other 
TLDs would be available for use in the Martian DNS system.

This idea started out with complete, discrete implementations of 
"Internet", including dedicated DNS roots, on Mars.  Adjustments have been 
made along the way to trim off unnecessary replication.  It sounds like 
you have an idea which can perform such a trim.  I appreciate it!
