It's because the idefix' canonical hostname (the one you get when  
performing a reverse dns lookup on its ip address) contains "adsl",  
which is automatically interpreted as "dial-up/dynamic ip address" by  
many servers.

There are more providers blocking mails from idefix for probably that  
reason, such as pochta.ru (which also handles email for several  
other .ru domains including rbcmail.ru, hotbox.ru and front.ru),  
web.de and ukr.net.
