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:

我尝试过评论

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

答案1
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,
},
});
