Get SMTP name by passing domain name in c#?

Question

Hi Team,

I have very basic question, i have a domain name for example yahoo.in with me. Now, i want to pass that domain name and get SMTP mail server name for example smtp.mail.yahoo.com. I want to get this by c# code.

My intention behind this, i have multiple of email addresses so i will pass domain name for a requested email address and fetch SMTP mail server name.

Please suggest code to get SMTP name by domain name.

Thanks in advance.
