This account works.

May be in seven days or never. That's not your fault.


That is the willful ignorance of some ISPs - speak IPv4, or we won't 
talk to you.


Last year the Deutsche Telekom was able to receive emails from 
IPv6-only-networks. Now they are completely disconnected from the 
internet, at least from emails point of view.
