Prioritize Bounced Email Notification

It seems weird to have to ask for this functionality. Humans make mistakes, computers are supposed to deal with them. If Zendesk's SMTP service fails to deliver an email to "joeuser@email.om" because "email.om" is unresolvable, it's absurd to not immediately add that result to the ticket and mark the ticket open. For the support request to just fall into the void and the customer nor the agent is none the wiser, that's just astonishingly unprofessional.

I'm just dumbfounded that this issue ever existed at all, and more so that people have been asking for it for YEARS and it's not implemented. This is basic functionality for a service that facilitates email interactions between people.

@Mike Bombich thanks for picking up the topic again. As you can see, we are waiting for a while already.

Add Fender Musical Instruments (aka Fender Guitars) to the list of clients in sore need of this feature and a bit surprised by its absence in the current solution. Thanks!

odd that a ticketing email software does not have this as a default. 

My team would love to see this feature available sooner rather than later. Hard to believe a fat-fingered email address just disappears into the oblivion under the current Zendesk structure without the agent being notified. A time resolution would be greatly appreciated by our team!

When will this feature be available?

Another up-vote for this capability.  I agree with previous commenters that it isn't acceptable for a customer service organization to be unaware that the communication with the customer is failing.

3 years on, and this is still a concern for multiple users, despite this being slated for development 'in the near future'.

If Zendesk can build a spam filter that can consume emails that have a 'no-reply' email, SURELY it shouldn't be too difficult to build a feature that consumes postmaster/non-deliverable notifications?

Why would I bother even using Zendesk if my email client can provide basic functionality that Zendesk seems to be unable or unwilling to replicate?

Honestly, give one of your developers two weeks of free time (maximum!) and I 'm sure they could build something usable.

This is a big issue and ridiculous that it is not native- PLEASE FIX ASAP!

+1 on this feature. We have got some angry comments from several clients, some ending on social networks with not so nice comments about our Brand, because their mails bounced each time we replied.
Deliverability events (webhooks our logs) are a common feature for mail delivery solutions and as Zendesk Support sens emails I Think this is really something you should include in not so distant releases.
