响应服务器554 5.7.1,554 5.7.1：中继访问被拒绝的centos后缀

我在centos中从postfix发送邮件时遇到问题

在链接中我尝试了以下命令

telnet localhost smtp

Trying ::1...

Connected to localhost.

Escape character is '^]'.

220 mydomain.com ESMTP Postfix

ehlo localhost

250-mydomain.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

mail from:

250 2.1.0 Ok

rcpt to:

554 5.7.1 : Relay access denied

编辑-1

在终端这工作

echo TEST | mail -v -s "Test mail" testing@gmail.com

我的postconf -n显示了belog信息

alias_database = hash:/etc/aliases

alias_maps = hash:/etc/aliases

command_directory = /usr/sbin

config_directory = /etc/postfix

daemon_directory = /usr/libexec/postfix
