SU Why does mail go into my spamfolder?

There are mainly 3 possible reasons for that.
1. The central spamfilter canit is triggerd. Read more about canit here.
2. Your local mailclients spamfilter is triggerd. The solution here is just to add the senders adress to your local adressbook.
3. In some rare cases i have discoverd that somehow the user managed to block senders in the webmailclient https://ebox.su.se . To fix this just do as follows: Login. In top far right corner, click on the cogwheel, choose alternative, choose block or allow. Check if anything is added to the blocked list that should not be there. In that case remove it.
