java - Outlook 禁止使用 R 中的 mailR 对某些电子邮件地址进行身份验证

Question

我正在尝试使用我公司电子邮件中的 mailR 在 R 中自动发送电子邮件(它不允许我标记 mailR，所以我用类似的包 sendmailR 标记它)。

我使用了这篇文章中的代码 ( Send authenticated mails via Outlook through R using mailR package )，虽然它适用于我的学校 Outlook 电子邮件，但不适用于我的公司:

send.mail(from = "me@companydomain.com",
to = c("coworker@companydomain.com"),
subject = "Test Email",
body = "Hi Coworker! Did this email send?",
authenticate = TRUE,
smtp = list(host.name = "smtp.office365.com",
port = 587,
user.name = "me@companydomain.com",
passwd = "Password1",
sls = TRUE,
tls = TRUE),
debug = TRUE)

我 100% 确定我使用了正确的用户名、密码等，但仅在使用我的公司电子邮件时收到此错误消息:

最后，因为我收到此错误，所以我打开了调试，这是它的报告。据我所知，我的电子邮件第一次经过身份验证并连接到服务器，但最后第二次身份验证失败。据我所知，除非幕后发生了某些事情，否则我们没有两因素身份验证。

我希望能够发送这些自动电子邮件，同时仍保持安全性。这可能吗？如果可能的话怎么办？我知道错误提到了 Java 中的东西，但我不知道，所以也许这就是关键？谢谢!

Answer 1

试试这个:

send.mail(from = "me@companydomain.com",
to = c("coworker@companydomain.com"),
subject = "Test Email",
body = "Hi Coworker! Did this email send?",
smtp = list(host.name = "companydomain.mail.protection.outlook.com", port = 25, user.name   = "me@companydomain.com", passwd = "Password1"),
authenticate = TRUE,
debug = TRUE)

请注意，我已将 SMTP 主机名从 smtp.office365.com 更改为 companydomain.mail.protection.outlook.com，并设置 port = 25 。

我是从 Microsoft 的 Office 365 文档页面了解到这一点的。
