[imp] Address lookup does not access favorite recipients

[Simon B]

Hallo,

Not sure if this goes to IMP, Turba or Horde...

When composing messages, the address look-up does not reference the
favorite recipients address book, even though this is correctly
populated with frequent recipients.

I.e. unless the email address is attached to a contact in turba, the
look-up does not return a match.

Is this something wrong with my configuration?  A bug?  Intended behaviour?

Thanks.

Simon
