Hi.

Some of our emails are sent using public folder address as sender. After migrating to Exchange 2013 this folders are flooded with NDR from non existent adressess. Is there some way to filter NDR, sent to public folders? I've tried transport rules and "folder assistant" without saccess.

Transport rule should be able to do it...what is your transport rule settings?

Hi,

I understand you don't want to receive the NDR on the public folder address.

Please try to use the below command :

New-TransportRule -Name 'test' -Comments '' -Priority '0' -Enabled $true -SentTo public@domain.com -SubjectOrBodyContainsWords 'generating server:domain.com' -DeleteMessage $true

Hope it's helpful to you.

Regards,

David

It seems transport rules do not work with Exchange system messages. 

I've tried subject and sender rulles but they just do not work.
