Question

我正在尝试使用公司电子邮件从R中自动使用mailR发送电子邮件（它不允许我标记mailR，所以我用类似的包sendmailR对其进行了标记）。

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

 private void pictureBoxPage_MouseDown(object sender, MouseEventArgs e)
            {
                if (e.Button == MouseButtons.Left)
                {
                    pictureBoxPage.Invalidate();
                    region.X = e.X;
                    region.Y = e.Y;
                    region.Width = 0;
                    region.Height = 0;
                }
            }

            private void pictureBoxPage_MouseUp(object sender, MouseEventArgs e)
            {
                if (e.Button == MouseButtons.Left)
                {
                    GetRegion(e);
                }
            }

            private void GetRegion(MouseEventArgs e)
            {
                if (e.X < region.X)
                {
                    region.Width = region.X - e.X;
                    region.X = e.X;
                }
                else
                {
                    region.Width = e.X - region.X;
                }

                if (e.Y < region.Y)
                {
                    region.Height = region.Y - e.Y;
                    region.Y = e.Y;
                }
                else
                {
                    region.Height = e.Y - region.Y;
                }

                pictureBoxPage.Invalidate();
            }

            private void pictureBoxPage_Paint(object sender, PaintEventArgs e)
            {
                e.Graphics.DrawRectangle(new Pen(Color.Red, 5), region);
            }

            private void pictureBoxPage_MouseMove(object sender, MouseEventArgs e)
            {
                if (e.Button == MouseButtons.Left)
                {
                    GetRegion(e);
                    pictureBoxPage.Invalidate();
                }
            }

我100％确保我使用了正确的用户名，密码等，但是仅在使用公司电子邮件时会收到此错误消息：

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)

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，我的电子邮件是第一次通过身份验证并连接到服务器，但是最后，它再次失败了。据我所知，除非引擎盖下发生任何事情，否则我们没有两因素身份验证。

我希望能够在保持安全性的同时发送这些自动电子邮件。这有可能吗？我知道错误提到Java中的内容，我不知道，所以也许这是关键吗？谢谢！

尝试一下：

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，并设置了port = 25。

我从Microsoft的Office 365文档页面中学到了这一点。

Outlook禁止使用R中的mailR对某些电子邮件地址进行身份验证
