I installed WP-Mail-SMTP and it′s works. the problem was in the email hosting with wordpress. Best regards!

Though the plugin successfully sends millions of emails every day, there are a host of issues that can stop or delay emails on both the sending and receiving ends. It depends entirely on your local Server & WordPress configuration. You will need to investigate this issue for your particular local configuration.

See Contact Form 7 Email Issues. Most people that work through this information appear to be able to resolve their email sending & receiving issues.

While jevaz found they had to install WP-Mail-SMTP, your particular problem and therefore solution is likely to be different.
