Exim4：“连接超时”--不管转发的smtp服务器是什么

Question

Exim是在公共云提供商提供的新提供的VM上配置的公共IP (scaleway.net)。

用途：

能够从CLI (或脚本)发送邮件给公共目的地收件人(gmail，yahoo，.)

结果：

Exim4日志文件/var/ log /exim4 4/mainlog显示与所有测试服务器(gmail、free.fr、online.net)的“连接超时”。

配置详细信息：

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.5 LTS
Release:    16.04
Codename:   xenial

• 服务器上没有配置防火墙，也没有云提供商的规则。
• 解析的smtp服务器IP地址(来自exim日志文件)是可单击的。

使用不同的smtp服务器进行测试：(gmail、free.fr、online.net)

/etc/exim4/update-exim4.conf.conf

我是不是漏掉了什么东西？

Answer 1

Scaleway默认情况下阻止传出SMTP。你需要将其从控制面板中解除。。访问此选项需要经过验证的帐户；如果无法启用该帐户，请打开带有Scaleway的票证以获得进一步的说明。
