So, we have an email address for the community, it's not anyones work email.
We are getting a handful of emails that bounce back due to what I've figured out is people no longer working at their job (I run a B2B community) where SSO is required and uses a work email.
While assuming is not ideal, my hunch is most people who've left their job will have very low interest in coming back to the community - or may not even be able to given we use SSO.
Anyway, I was looking for ideas on how to handle those users.
I'd just ignore them, TBH. Make sure your reply-to email address from community notifications is an un-monitored email address (e.g. firstname.lastname@example.org) and then just let those bounce emails fly!
