iRedmail 服务器推迟从另一台内部服务器发送的邮件

iRedmail 服务器推迟从另一台内部服务器发送的邮件

概要:

4个独立服务器:

一个 iRedMail 服务器(new-domain.com)

一个应用程序(existing.com)

单节点电子邮件发送器(中继)

一个节点实例充当 iRedMail 服务器的电子邮件密码管理器

情况:

通过 Thunderbird、Outlook 或 Roundcube 发送至 new-domain.com 和从 new-domain.com 发送的所有邮件均运行良好。

从电子邮件密码管理器通过中继发送到 new-domain.com(驻留在那里的帐户)的邮件被延迟,我不知道原因。

我尝试过在中继器上更改 main.cf、master.cf 中的设置

来自中继服务器的日志条目:

尾部-f /var/log/mail.log:

Dec 11 16:08:39 email postfix/smtp[24014]: 46430204C: to=<[email protected]>, relay=none, delay=30, delays=0.08/0.03/30/0, dsn=4.4.1, status=deferred (connect to new-domain.com[12.34.56.78]:25: Connection timed out

我尝试过评论

-o smtpd_relay_restrictions=permit_sasl_authenticated,reject

在 new-domain.com 上的 /etc/postfix/master.cf 中 - 无济于事

下一步我应该尝试什么?

解决了: 事实证明,我需要做的就是从 iRedMail 服务器上的已知用户发送邮件,并在 nodemailer 中的电子邮件程序上对他进行身份验证。例如,这是我在 nodemailer 中的代码:

let transporter = nodemailer.createTransport({
    pool:true,
    host: 'mail.new-domain.com',
    port: 587,
    secureConnection: true,
    auth : {
        user : '[email protected]',
        pass : 'password'
    },
    tls: {
        rejectUnauthorized: false,
    },
});
