从终端向 Gmail 发送邮件不起作用

你好，我尝试使用 sendmail 从我的 centos 终端发送电子邮件，但它不起作用，我使用默认配置的命令，因为我只想发送电子邮件。我需要帮助。接下来我使用[电子邮件保护]，这将是我想要发送电子邮件的真正的 Gmail 用户。我所做的是：

[root@localhost ~]# echo "Subject: sendmail test gmail" | sendmail -v [email protected] 
[email protected]... Connecting to [127.0.0.1] via relay... 
220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Fri, 3 Jun 2016 16:56:01 -0300
>>> EHLO localhost.localdomain 250-localhost.localdomain Hello localhost.localdomain [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-DELIVERBY 250 HELP

>>> QUIT 221 2.0.0 localhost.localdomain closing connection

但是 gmail 收不到邮件，而且我在日志中看到 verify=fail。/var/log/maillog 显示：

答案1

邮件实际上已被 gmail 端接受。最后一行显示了这一点，您会从接收服务器收到以下内容：OK 1464983764 l40si4464056qtc.52 - gsmtp

verify=fail 与 TLS 协商有关（我认为客户端证书验证失败，这通常不会强制执行）。

我首先想到的是，您的邮件可能会被丢弃，或者至少根据您的发件人地址被添加为垃圾邮件。此外，如果您的服务器没有配置 PTR 记录，则服务器无法进行反向查找以验证您是发件人，这也可能会将其标记为垃圾邮件/非合法邮件。

首先尝试指定一个有效的发件人/发件人地址，看看是否允许它到达。
