tells that the problem is with the MX record of and/or the 
HELO message of the smtp server. At least one of them is said 
to be RFC ignorant, and this is why the recipient is on the blacklist. 
Without making those changes, the domain will not be removed 
from the blacklist. Changing the MX record / configuring the SMTP server 
needs to be done by the DNS or SMTP admin of

At least I think if I ask to remove the entry, the first thing 
they will do is check if the changes has been made.
