XF 1.4 Bounced emails


I am using Mailgun for transactional emails. So far, so good.
Some of my users have not updated their emails for years and messages bounce.

How do you guys handle this?
Is there a way to automatically send them a conversation or display a notice asking users with outdated emails to update their info? (or a better idea)


So I have to setup my DNS for receiving emails from Mailgun as well I guess?
Then use my Mailgun info in the Bounced Email Handler, correct?

I'm so happy that this feature exists!

Scratch that, that was silly, there can't be 2 diffrent records for receiving emails :)
I guess I need to figure out how to grab bounces from Google Apps.
