Is there any approach to stop the auto reply e-mail (User has set up OOO message

We dont want to recieve any message from the user.
We have an email node which sends email to set of users in a group and lets say if one user of that group has set up OOO message, simply auto reply. His OOO message triggers as soon as he receives an email from Appian, then he gets an undelivered email which user doesnt like to see. So what is the possible approach for receiving auto emails?

Thanks!
