请大家帮忙看一下为什么不能发信
简单说一下，我原先有一台Mail Server，RedHat 9.0做的服务器(MAIL)，收发信正常，后来因为用户增多，所以准备增加一台专门用来发信件的服务器（SMTP) ,用CentOS 4.4做的服务器。现在做好后，发信时有如下提示，用OUTLOOK
由于服务器拒绝收件人之一，无法发送邮件。被拒绝的电子邮件地址是“[email=mis@gd.um.com]mis@gd.um.com[/email]”。 主题 'test', 帐户: '172.16.86.1', 服务器: '172.16.86.5', 协议: SMTP, 服务器响应: '550 <[email=mis@gd.um.com]mis@gd.um.com[/email]>: Recipient address rejected: User unknown in local recipient table', 端口: 25, 安全(SSL): 否, 服务器错误: 550, 错误号: 0x800CCC79
服务器上日志如下：
Dec 22 07:14:03 smtp postfix/smtpd[9652]: NOQUEUE: reject: RCPT from unknown[172.16.86.60]: 550 <[email=mis@gd.um.com]mis@gd.um.com[/email]>: Recipient address rejected: User unknown in local recipient table; from=<[email=wht@gd.um.com]wht@gd.um.com[/email]> to=<[email=mis@gd.um.com]mis@gd.um.com[/email]> proto=SMTP helo=<T1112>
Dec 22 07:14:03 smtp postfix/smtpd[9652]: disconnect from unknown[172.16.86.60]
我的原正常服务器设置如下：
[root@mail named]# more /etc/named.conf
// generated by named-bootconf.pl
options {
directory "/var/named";
forwarders{
10.0.0.1;202.96.128.68;
};
//forward-only;

* port by default.

// query-source address * port 53;

unknown_local_recipient_reject_code = 550 最怵头的邮件啊……同情。 没有作企管的朋友知道吗？都在用噢 实在怕邮件的配置。
你已经确认你的服务器能被访问了？端口已经在listen了？telnet的时候能够看到相关信息了？
