使用 gmail 的 MailR 出现“没有合适的协议”错误

编程问答 2022-05-02

问题描述

我正在尝试使用 mailr 从 Gmail 帐户发送一封简单的电子邮件：

send.mail(from = "XXXXXX@gmail.com",to = c("YYYYYY@gmail.com"),subject = "Subject of the email",body = "test",html = TRUE,inline = TRUE,smtp = list(host.name = "smtp.gmail.com",port = 465,user.name = "XXXXXX",passwd = "XXXXXX",ssl = TRUE),authenticate = TRUE,send = TRUE)

它给了我以下错误：

org.apache.commons.mail.EmailException: Sending the email to the following server Failed : smtp.gmail.com:465

我只是将不安全的应用程序访问权限更改为是，但没有任何反应。
