我一直在玩弄 mailR 包以从我的 Gmail 帐户发送电子邮件，但到目前为止我一直无法使其工作。代码如下（为了隐私/安全，将电子邮件和密码替换为“aaaa”）：

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)

据我了解，这似乎是该软件包的适当设置。此外，我已确保关闭双重登录并启用“允许不太安全的应用程序访问”。我也尝试过使用 tls 和 ssl （带有适当的端口），这并没有什么不同。

当我运行代码时，出现以下错误：

知道出了什么问题吗？

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

鉴于您已要求使用该mailr软件包提供故障排除解决方案，这不是一个完整的答案，但如果您愿意尝试另一个软件包，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)

当您使用该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，使用您通过公共应用程序连接的 gmailR 包。

通过在终端中输入“是”并在浏览器中单击“接受”，您将.httr-auth在当前工作目录中存储令牌（加密的用户名和密码）（为什么我们在开头设置工作目录）。list.files(all = T)您可以通过在终端中运行来查看该文件。这允许您重新运行代码，而无需 a.) 在物理代码中存储您的用户名和密码，以及 b.) 以交互方式“重新接受”连接。
