从c＃中的域名获取SMTP详细信息？ [英] Get SMTP detail from domain name in c#?

问题描述

Hi Team，



以下是我的工作代码 -



MailMessage mail = new MailMessage（ ）;

mail.To.Add（[e-mail]）;

string fromEmail =[e-mail];

mail.From = new MailAddress（fromEmail）;

string [] split = fromEmail.Split（'@'）;

string domainName = split [1]。 ToString（）;



mail.Subject =使用任何SMTP发送电子邮件;



string Body = 这封邮件是用ASP.NET中的任何SMTP测试发送邮件+;

mail.Body = Body;



mail.IsBodyHtml = true;

SmtpClient smtp = new SmtpClient（）;

smtp.Host =smtp.mail.yahoo.com;

smtp.Credentials = new System.Net.NetworkCredential（[e-mail]，*********）;

smtp.EnableSsl = true;

smtp.Send（mail）;



此代码完全适用于Yahoo SMTP服务器。现在我的要求是什么，



假设，我有hotmail，gmail或任何其他电子邮件地址，我会将其域名转换为domainName变量。我想在该域名上获取SMTP邮件服务器名称并将其传递给smtp.Host值。通过这种方式，我希望保持我的代码动态。



有人可以建议我如何在域名的基础上获取SMTP邮件服务器名称吗？



请建议。

Hi Team,

Below are my working code-

MailMessage mail = new MailMessage();
mail.To.Add("[e-mail]");
string fromEmail = "[e-mail]";
mail.From = new MailAddress(fromEmail);
string[] split = fromEmail.Split('@');
string domainName = split[1].ToString();

mail.Subject = "Email using any SMTP";

string Body = "Hi, this mail is to test sending mail" + "using any SMTP in ASP.NET";
mail.Body = Body;

mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.mail.yahoo.com";
smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "*********");
smtp.EnableSsl = true;
smtp.Send(mail);

This code is perfectly working for Yahoo SMTP server. Now what is my requirement here,

suppose, i have hotmail,gmail or any other email address, i will get it Domain Name into domainName variable. I want to get SMTP mail server name on that Domain Name and pass it to smtp.Host value. In this way i want to keep my code dynamic.

Can anyone suggest me the approach for how to get SMTP mail server name on the base of Domain Name?

Please suggest.
