Question

我已经仔细研究了可能的解决方案列表，但我没有看到这个问题。

我在crontab条目中使用smtp多年了，以通过电子邮件提供状态更新。然后它在本周退出了，我无法修复它。然后我看到它已经变成孤立的了，建议是转移到msmtp。因此，我将其下载并安装在Ubuntu 18.10系统上。

我正在尝试将电子邮件发送到myaccount@gmail.com帐户。看来我正在与gmail smtp服务器正确通信，如下面的调试所示。但是它总是会得到一个TLS超时。

我也不明白为什么我有多个EHLO条目。我的系统没有DNS域名，所以我不确定在这里输入什么。本地主机似乎工作正常。另外，我的Thunderbird电子邮件收发器可以正常使用gmail。

Here's the debug output:

echo "Hello there" | msmtp --debug myaccount@gmail.com >/tmp/msmtpOut.txt

Answer 1

使用--with-tls=openssl构建msmtp来解决问题。

关于EHLO命令发送了两次RFC3207状态：

服务器必须舍弃任何知识从客户端获得的信息，例如EHLO命令的参数，这不是从TLS协商本身获得的。客户端必须丢弃从服务器获得的任何知识，例如列表并非从TLS获得的SMTP服务扩展名谈判本身。客户端应该发送EHLO命令作为 TLS协商成功后的第一个命令。

这是正常的行为。
