Wie E-Mail funktioniert..

I have recently been questioned about how bounces can be harmful if a receiver doesn't send back the right information. These discussions have been difficult for me because many people question why ESPs can't just magically know if they are incorrect. Some receiving mail/message transfer agents (MTAs) do report the wrong thing and as such might invalidate a good email address for you, but on the flip side, the sender should never second-guess it since it could be a true invalidation. This is one of those age-old questions that has haunted the sending community for decades now. What do you do?

This is an interesting conversation to have with those who don't understand the bounce standards. So we're going to have a look at how bounces and MTAs work. No, this is not a show on the Discovery Channel for you "How Stuff Works" fanatics, nor is this a slap in the face to those who know how to type and hit "send" in a simple email client. This is more of a "behind the scenes" look at the inner workings of email itself
