Jabber Psi+ message history

There's openfire-4.0.2 IM sender connected to Samba AD server. As a jabber client Psi+ v0.16.330 is used.

When User1 sends message to User2 this outgoing message doesn't written to User's1 message history. But User2 in his history has message from User1. In other words, all histories of all users contains only incoming messages, not the full "dialog".

In "Account" settings in Psi+ checkbox "Keep history" is on. "History Keeper" plugin is turned off.

What's wrong?
