Question

我一直在使用mailR软件包从我的Gmail帐户发送电子邮件，但到目前为止我一直无法使其正常运行。代码如下（电子邮件和密码被'aaaa'替换为隐私/安全性）：

library(mailR)

sender <- 'aaaa@gmail.com'
recipients <- c('aaaa@gmail.com')
send.mail(from = sender,
              to = recipients,
              subject = 'My bot sent this',
              body = 'Test Successful',
              smtp = list(host.name = 'stmp.gmail.com', port= 587,
                               user.name = 'aaaa@gmail.com',
                               passwd = 'aaaa', tls= TRUE),
              authenticate = TRUE,
              send = TRUE)

根据我的理解，这似乎是适合此套餐的设置。此外，我已确保关闭双重登录并启用“允许访问安全性较低的应用程序”。我也尝试了tls和ssl（配有适当的端口），这没有什么区别。

当我运行代码时，我收到以下错误：

知道出了什么问题吗？

Answer 1

鉴于您已使用mailr软件包要求解决问题解决方案，但不是完整答案，但如果您打算尝试使用其他软件包，请使用gmailr。

install.packages('gmailr')
library(gmailr)
setwd() #set to desired working directory
gmail_auth()

mail <- mime(
  To = "to_address@domain.com",
  From = "from_address@domain.com",
  Subject = "My bot sent this",
  body = "Test successful")
send_message(mail)

当您使用gmail_auth功能时，它会以交互方式询问您是否要连接到您的Gmail帐户。请注意使用通过公共应用程序连接的gmailR包。

输入“是”＆＃39;在终端中点击“接受”＃39;在浏览器中，您在当前工作目录中存储.httr-auth令牌（加密的用户名和密码）（为什么我们在开始时设置工作目录）。您可以通过在终端中运行list.files(all = T)来查看该文件。这使您可以重新运行代码，而无需使用。）将您的用户名存储在物理代码中，并且b。）重新接受＆＃39;交互式连接。

Answer 2

您插入了错误的主机名：host.name = 'stmp.gmail.com' 该协议是smtp，因此host.name = 'smtp.gmail.com'
