Read the docu on the $prefs array, in horde/config/prefs.php.
Then look at one of the example involving an enum, e. g. date format:
you will see that the static list of possible values goes into
the ['enum'] component, whilst the ['value'] component contains
the value actually selected.

As you can also read, the hook function will be used to supply the
['value'] component. So, you have not supplied any enumeration.
If you want to supply a more dynamic list, you'd have to explicitely
call a function directly from horde/imp/config/prefs.php to obtain
that list and assign it directly to the ['enum'] component.

Originally, $_prefs['tieto_addr'] has
     'type' => 'textarea',
I guess you are not allowed to change this, as you could
invalidate some code targetted at interpreting that very
value. Could any person in the know (Jan?) elaborate on
this issue?

For a starter, you could try
   'type' => 'textarea',
   'value'=> "test1 at kwsoft.com\ntest2 at kwsoft.com",
(i. e., a single string containing a newline-separated list).
But then I have not the slightest idea what purpose
$_prefs['tieto_addr'] is meant to serve, and whether this
preference will fit your bill.
