我刚装好Exchange 2003 在使用outlook pop3模式下发送外部的邮件总是出现
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'username@abc.com'. Subject 'mail test4', Account: 'username@zxc.com', Server: 'zxc.com', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for username@abc.com', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
但是发给我内网的邮件地址就可以发出去,已经确定smtp 25端口在路由器里面打开了。这个是什么问题啊
另外我用telnet 测试25端口会出现
