thanks for help and sorry for my bad english.

This isn't a Roundcube problem, its a problem with your mail server. Also as a side note you really should upgrade Roundcube version 0.7.2 is very outdated.

How i can upgrade? for install i use apt-get install rounducbe xDD

I would recommend not using Roundcube from your distro's repo because they are often out of date. You can try to update normally https://github.com/roundcube/roundcubemail/wiki/Upgrade but you may run into problems depending on how the package worked.
