It going to take some work by staff to remove all the undeliverable emails but once you get the initial brunt of them there will be only a hand full with each new mass email and its completely manageable .

If vbulletin would remove bounced emails and notify the user of this situation instead for keep trying to email to them OVER AND OVER for thread notifications and pm's and mass emails ect... this mod wouldn't be needed at all .

What a waste of resources when the system is trying to email to accounts that you know are invalid !

there must be a setting some where on vbulletin or server side that states rather you wish to receive undeliverable email notifications . i did not get them on my VPS but i get them on my dedicated so im thinking this is server side , i suggest turning this on so you can identify the invalid emails your users have and prompt them to update/repair them.
