My Server doesn't send any email to other domains except to Gmail.com

Hi guys,

My server sends the email to GMAIL.COM. If I try to send an email to my Yahoo mail address or if I send an email to an address with .ru extension it will be never received by the recipient.

Some messages: /var/log/maillog
