Filtering out-of-office/auto replies from our subscribers so that they don't flood our inbox was a feature we had in Marketing Cloud. Unfortunately, it looks like without purchasing an additional plugin (Siftrock is the only option we've found), we now have to receive all these to our reply-to email each time we send a marketing communication.
It would be very helpful to have some sort of reply-management option/filter in Marketo, which seems to be standard in other major email service providers.
