Turn off NDR?
How do I disable NDR notices in Zimbra?
I'm running 6.0.5.
Under heavy attack right now. I've implemented some of the other postfix settings found here on the server but need to turn off the sending of these Non Deliverable Receipts.
Any way of doing this?
Thanks so much for ANY help!
but I've got an aliased domain as well and all these messages seem to be targeted at the aliased domain.
If by 'alias domain' you mean you have a catch-all address on the domain then you're seeing exactly why they're a bad idea. By definition you will not be able to reject email for non-existent addresses when a catch-all is designed to let all that email in. You need to give specific details of what you exactly done from the wiki article on Managing Domains and whether you've followed this: Managing Domains - Zimbra :: Wiki

You need to give some information about what changes you've made to your system (do you have a catchall as mentioned in my previous post), any modifications to the anti-spam system and if so what were they? Have you looked at some of the threads in the forums that cover 'backscatter' spam and what can be done about it? Do you have any RBLs? Which version of Zimbra etc. etc.
