In this post I want to show How we can send mail with reply to option in .NET. I means, for example we sent auto mail to site user using no-reply@domain.com. But That user need you support, then mail content. So he will try to use reply option for that mail. once he/she click on reply button, it will add To: text with reply@domain.com here we can't see same id(no-reply@domain.com). Or sometimes we need to set job to look reply mail by another person that time we can use this option. I hope some...
