Unfortunately legitimate email is sometimes also rejected.
If it was rejected due to filtering please try to send the email again from an alternative server (like yahoo or hotmail).
If it was rejected since the email adress was changed please find the new one at:
www.eit.se/users
If you have no alternative server you can check this page for alternative communication (like phone):

If you are a spammer please try one of the email adresses on this page:
s.p-m adresses
Best wishes
