No, I don't use earthlink, in this case the provider happens to be 
1and1.com.  I use speedfactory for the majority of my services.

I did contact 1and1.  But the problem is not them.  The receiving email 
address was the mindspring address, not the sender.  It's mindspring 
who's sending the thing back, apparently based on the headers.

I checked the rfc, I must have missed it.  I don't understand why the 
mail headers should compromise the nat'ing.

BUT this makes no sense.  I'm doing what they want me to do, using my 
isp mail server rather than my own.  I can use my own and that get's 
through.

But when I send email from localhost, it doesn't place my static in the 
headers, but my domain, which is 3times25.net, which will properly 
resolve. The problem is that mozilla is sticking the internal nat'd 
address in the headers.  Personally, I don't think this should be done. 
  It's complicated by the fact that the email address in question is not 
of my domain, it's a different domain.  If I send email from 
esoteric at 3times25.net I don't have the problem, it's only when I send 
email via a different domain when I have the problem.  The other domain 
is a valid domain, so reverse lookup works.  The problem stems from the 
nat'd address showing up in the headers.
