我現在有一臺Mail Server ,可以正常收發郵件,沒有問題.是用Linux 9.0 + Postfix做的
而我還要建立一臺Mail Server專門作為發送郵件的服務器,是用CentOS + Postfix,
目前用CentOS這臺發送郵件時總是發送不出去,揭示"unkown user"
錯誤日志如下：
Dec 22 07:14:03 smtp postfix/smtpd[9652]: NOQUEUE: reject: RCPT from unknown[172.16.86.60]: 550 <mis@gd.um.com>: Recipient address rejected: User unknown in local recipient table; from=<wht@gd.um.com> to=<mis@gd.um.com> proto=SMTP helo=<T1112>
Dec 22 07:14:03 smtp postfix/smtpd[9652]: disconnect from unknown[172.16.86.60]
以下兩臺server的設定檔.
