When i connect from telnet to port 25 i write mail from all it's ok, but when i write rcpt to, then receive temporary lookup failure. For mail server configuration i used this tutorial https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql/
I can connect to pop3 without any problem, all works fine, but smtp i have problem and sending e-mail.
I don't know what is wrong with my configuration. Log from /var/log/mail.log
