[horde] From field problem

[Vesku]

Hi,

Horde 3.3.4, IMP 4.3.4
I'm having problems with From field in Options=>Personal information. I'm
using custom hooks to create full name and from field. They work fine when
using IMP, compose message window From field is correct. But in Options the
>From field only shows name part, @domain.com ending is missing. I've tried
to go through all the settings but for some reason services/prefs.php does
not get the right From field.
Full name field is correct. I can't make any changes to Options unless this
is solved. Horde complains From field is not valid, which is correct since @
domain.com ending is missing.
Is this is a bug or am I missing something here?
