我是sendmail上的一个绝对的newB,现在我安装了sendmail,configuration了它(据我所知)添加了localhost-names,增加了访问条目,添加了virtuser条目,在iptables中打开了端口25。
我的DNS正在指向我的服务器!
现在当我从互联网上的另一个地方连接,并使用telnet server.com 25并使用手动SMTP命令(HELO,MAIL From等)时,邮件就会到达并被传送到合适的用户。 但是当我使用另一个客户端,并通过(例如谷歌)传递我得到这个错误:
中继拒绝。 需要正确的身份validation。 (状态14)。
我忘了什么设置? 任何configuration文件,我需要发布,所以你可以帮我吗? 我使用CentOS 5.5和最新的sendmail rpm

根据你的sendmail.mc你的sendmail安装支持SMTPauthentication和STARTTLS。 当您在端口25上“手动”(telnet)连接时,您没有使用任何这些选项。 但是,似乎您的客户端已设置为连接到您的sendmail服务器,并使用SMTP身份validation或STARTTLS(或两者)和您的服务器,虽然它宣称支持这些选项,但没有正确configuration。
让您的客户端连接到服务器的端口25,并取消任何启用STARTTLS,SSL,TLS或SMTP-AUTH的选项。 您的其他select是在阅读sendmail文档后正确configuration它们。
使用SMTP授权(本地login和密码):
AUTH PLAIN base64("\000email\000password")
或者接受在/ etc / mail / access中继你的ip
192.168.1.1 RELAY
然后创build映射“makemap hash /etc/mail/access.db”/ etc / mail / access“
