postfix Relay access denied问题

postfix用客户端外发游戏出现Relay access denied，拒绝发信

解决办法：

编辑/etc/postfix/main.cn，找到

smtpd_recipient_restrictions=permit_sasl_authenticated, 
    permit_mynetworks, 
    reject_unauth_destination,

修改为

smtpd_recipient_restrictions = permit_sasl_authenticated, 
        permit_mynetworks, 
        reject_unauth_destination,
	reject_non_fqdn_sender,
        reject_non_fqdn_recipient, 
        reject_unknown_recipient_domain
