Sendmail 8.15 未重写发件人域

Sendmail 8.15 未重写发件人域

RHEL 8 系统上的 Sendmail 8.15。我可以发送邮件,但当我在另一端收到邮件时,“发件人”地址是 user@FQDN,而不是 user@MASQUARADE_AS

我们得到的是:[电子邮件保护]

我们想要的是:[电子邮件保护]

sendmail.mc 配置包含这些以及其他宏:

MASQUERADE_AS(`somedomain.com.au')dnl
LOCAL_DOMAIN(`localhost.localdomain')dnl
EXPOSED_USER(`root')dnl
FEATURE(masquerade_envelope)dnl
MASQUERADE_DOMAIN(somedomain.com.au)dnl

出于管理原因,我们确实希望将 root 用户显示为来自 FQDN 的用户,但我们希望所有其他用户显示为 user@MASQUERADE_AS,

测试配置,事情正如它们应该的那样出现:

final            returns: user @ somedomain . com . au

我很困惑。我还需要查看其他配置指令吗?

是的,我在编辑 sendmail.mc 文件后确实运行了“make”。:)

somedomain.com.au 是我们邮件的外部可见出口点(spf 记录等)的 MX。

============================

使固定:

所以...我们最终通过这种方式解决了它:

发送邮件.mc:

FEATURE(masquerade_envelope)dnl
FEATURE(masquerade_entire_domain)dnl
FEATURE(masquerade_entire_domain)dnl
MASQUERADE_AS(`somedomain.com.au')dnl
MASQUERADE_DOMAIN(localhost)dnl
MASQUERADE_DOMAIN(localhost.localdomain)dnl
MASQUERADE_DOMAIN(`otherdomain.com')dnl
MASQUERADE_DOMAIN(`somehost.otherdoamin.com')dnl

提交.mc:

dnl define(`confDIRECT_SUBMISSION_MODIFIERS',`C')dnl

然后重新编译并重新启动,现在我们得到了所需的行为:外部用户会看到我们的邮件来自 somdomain.com.au
