Managesieve-filter not working.
The filter was working before upgrade to Roundcube 1.0.2 from 1.0.0. I've upgraded to 1.0.3. The problem is still there.

1. user1@iredmail.srv recives mail.
2. Managesieve-filter >> sends copy to  user2@iredmail.srv and user@externalmail.srv
3. user@externalmail.srv recives the mail but user2@iredmail.srv don't.

How should I proceed troubleshooting?
Where does the email dissapear? user2@iredmail.srv never receives the forward.
I've tryed recreate the filter.

According to the logs it's working, but the email is not delivered to "sub box" or "inbox".
