我试图设置postfix能够发送/接收邮件，我能够接收邮件，但是当我发送到任何其他领域，而不是我在postfix中设置的域名，我得到以下错误：
Jun 12 12:25:03 DEMISED postfix/smtpd[32291]: warning: hostname IN-213-226-141-251.somehost.com does not resolve to address 213.226.141.251: Name or service not known Jun 12 12:25:03 DEMISED postfix/smtpd[32291]: connect from unknown[213.226.141.251] Jun 12 12:25:06 DEMISED postfix/smtpd[32291]: NOQUEUE: reject: RCPT from unknown[213.226.141.251]: 554 5.7.1 <*******@gmail.com>: Relay access denied; from=<k@d****.net> to=<*****@gmail.com> proto=ESMTP helo=<[10.49.177.2]> Jun 12 12:25:07 DEMISED postfix/smtpd[32291]: disconnect from unknown[213.226.141.251] 我的main.conf ：

我希望能够发送电子邮件到任何域名，而不仅仅是我的域名，我怎么能做到这一点？ 谢谢！
更换
smtpd_relay_restrictions = reject_unauth_destination
同
smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
这是一条线
和这样的评论
#smtpd_sender_restrictions = reject_unknown_sender_domain
同
在main.cf中
