Stoped working.
I had a forward file in /var/qmail/aliases before, since the pseudonym seemed to work, i deleted those files, and now things have stoped working.
I put those files back, and it seems to work again..
It seems the files in /var/qmail/aliases need to be there and be valid, but it still ignores the addresses and uses the one setup as a pseudonym in the web interface..
All very confusing..
