标题: sendmail 问题 [打印本页] 作者: tangrui 时间: 2004-06-11 11:16 标题: sendmail 问题 我的sendmail是8.12.6
服务器放在dmz区，通过防火墙的端口映射对外提供服务。
现在发现一个问题：
1、在内部发信正常，但是在外网通过服务器发信则会出现下面的错误。
550 5.7.1 <XXXXXX@domain.com>;... Relaying denied. IP name lookup failed [61.128.153.163]
2、在内网给某些地址发信会出现。

<<< 550 Sender verify failed
550 5.1.1 <gertrude_zijl@ymd.yamaha-motor.nl>;... User unknown <<< 503 valid RCPT command must precede DATA
但是问题2还不知道怎么解决。
问题2的原因，我分析是对方的邮件服务器做了IP地址与域名的检查。因为我们的邮件服务器的IP信息是发送人本机的IP，所以与解析的IP地址不一致造成不能发信到该邮件服务器。不过解决的方法还希望有人能够告知。谢谢了作者: tangrui 时间: 2004-06-15 15:46 标题: sendmail 问题 UP作者: tangrui 时间: 2004-06-18 15:05 标题: sendmail 问题 2、在内网给某些地址发信会出现。
