使用 mailR 通过 Gmail 发送电子邮件时出错

Question

我正在尝试使用mailR包和 gmail 从 RStudio 发送电子邮件。 以下是我的代码...

library(mailR)
sender <- "xxxxx@gmail.com"
recipients <- c("xxxxx@gmail.com")
send.mail(from = sender,
          to = recipients,
          subject = "Test mail from Rstudio",
          body = "Test email body",
          smtp = list(host.name = "smtp.gmail.com", port = 465, 
                      user.name = "xxxxx@gmail.com",            
                      passwd = "******", ssl = TRUE),
          authenticate = TRUE,
          send = TRUE)

我收到以下错误消息...

Error: EmailException (Java): Sending the email to the following server failed : smtp.gmail.com:465

我到底做错了什么？ 错误消息中提到的谷歌链接不存在。

编辑：收到一封来自谷歌的电子邮件，内容是“登录尝试被阻止：有人试图从不符合现代安全标准的应用程序登录......”

有没有办法解决这个问题？ 谷歌电子邮件没有说明允许我从 R 发送消息。

Answer 1

在此处启用对“安全性较低的应用程序”的访问：

http://www.google.com/settings/security/lesssecureapps

Answer 2

我已经仔细阅读了这个和其他线程。 我下载了正确的 Java（64 位），java env 的路径是正确的，没有在 gmail 上设置 2FA，“不太安全的应用程序”访问是打开的，但既不是通过 SSL + 端口 465 也不是通过 TLS + 端口 587 am i能够发送电子邮件，我收到了与上述内容和其他问题线程类似的错误，这些错误似乎可以通过 2FA 问题或“不太安全的应用程序”问题解决 - 这个问题似乎不同......真的很感激这方面的一些帮助，已经在上面花了好几个小时而且无处可去。
