【问题描述】:
我希望有人可以在这里帮助我:
用户通过我的 asp.net 网站生成电子邮件。电子邮件将通过 365 服务器使用我在我的域中拥有的帐户(例如 out@mydomain.com)发送出去。我希望消息“发件人”字段是我的用户的电子邮件(例如,myuser@anotherdomain.com),以便电子邮件的接收者将他的电子邮件视为发件人并直接回复他。
但是当我尝试这个时,我收到一条错误消息(见下文)。
当“发件人”字段是我域中的另一个现有邮箱(例如,myname@mydomain.com)时,即使我尝试发送电子邮件,我也会收到相同的错误消息
如果“发件人”与用户名不同,显然有人挡路(不确定是 asp.net 还是 365 服务器)阻止电子邮件。
有没有办法解决这个问题>
这是我的代码
protected void btnSend_Click(object sender, System.EventArgs e)
{
AuditLog.Info("here");
try
{
string EmailContent = "test";
MailMessage msg = new MailMessage();
msg.IsBodyHtml = true;
msg.From = new MailAddress("myuser@anotherdomain.com");
msg.Bcc.Add(msg.From);
string email = "receiver@gmail.com";
msg.To.Add(email);
msg.Subject = "TEst 365";
System.Net.Mail.AlternateView plainTextView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(EmailContent);
System.Net.Mail.AlternateView htmlView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(EmailContent);
msg.AlternateViews.Add(plainTextView);
msg.AlternateViews.Add(htmlView);
System.Net.Mail.SmtpClient client = new SmtpClient();
client.Host = "smtp.office365.com";
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = "out@mydomain.com", "MyPassword");
client.Port = 587;
client.EnableSsl = true;
if (client.Host.Trim() != "")
client.Send(msg);
}
catch (Exception ex)
{
AuditLog.Info(string.Format("Failed to send mail . Error={0} ", ex.Message));
}
finally
{
AuditLog.Info("end");
}
}
这是错误:
