They are moved into the unwanted box, so I was able to view the message 
and headers from there.

The interesting part for me is that this problem only applies to mail 
sent through mailman, if I'm sending an email to the same address from 
the same domain name it is accepted without a problem, so I'm thinking 
that there is something in the headers that triggers this reaction at 
outlook.com.

p.s. the messages are accepted without a problem at gmail.com (I haven't 
tried any other major mail providers).
