As testuser you don't have write permission to /var/mail. To remove
a file from that directory (i.e. /var/mail/ullhan63), you would need
to change (i.e. write to) the directory.
You can, as testuser write to the file /var/mail/ullhan63, but you
can't remove it.
You could make it empty by
echo -n '' > /var/mail/ullhan63
or some moral equivalent.
