I've recently migrated our Exchange 2010 DAG to a Exchange 2013 DAG CU8, the migration went fine, mailflow is working as it should and so on.
But after migrating the public folders, I've begun to receive NDR mails, which i didnt before.
We are sending alot of mails from our systems (Using a SMTP service and a smart host) and these mails all have reply addresses which belongs to public folders so costumers can reply to them and our support team can handle incomming questions.
Some of these mails are sent to addresses that doesnt work, either because the addresses are typed wrong or the recipients have issues with their mail.
But we dont want to get NDR's because they are not being used for anything, so my question is if its possible to disable NDR's for public folders so they reject them when received or if they could be removed automatically.
I've tried with public folder assistant rules and also mailflow rules, for instance, if subject or body includes "Undeliverable: Mail Delivery Failure" then delete the message, but this does not work.
Does anyone have a good solution for this?
