R mailR包发送消息给STMP服务器（gmail）

Question

我一直在用mailR软件包来从我的Gmail帐户发送邮件，但到目前为止我一直无法使它工作。其代码如下（与隐私/安全“AAAA”取代电子邮件和密码）：

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) 

从我的理解，这似乎是一个适当的设置为这个包。此外，我已确保双重登录已关闭，并且已启用“允许访问不太安全的应用程序”。我也用tls和ssl（完成适当的端口）尝试了这一点，这没有什么区别。

当我运行代码，我得到了以下错误：

为了记录在案，这里是回溯输出，以及：

任何想法是怎么回事？

Answer 1

由于您要求使用mailr软件包提供故障排除解决方案，因此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，如果你想连接到您的Gmail帐户，将交互询问。请注意，使用通过公共应用程序连接的gmailR软件包。

通过在终端中输入'yes'并单击浏览器中的'接受'，您将在当前工作目录（为什么我们将开始设置工作目录）中存储一个.httr-auth标记（加密用户名和密码）。您可以通过在终端中运行list.files(all = T)来查看文件。这允许您重新运行代码，而无需执行。）将物理代码中的密码存储在您的用户名中，并b）以交互方式“重新接受”连接。

Answer 2

您插入错误的主机名：host.name = 'stmp.gmail.com' 该协议是SMTP，所以host.name = 'smtp.gmail.com'
