Need advice for NDR settings.

Post by armo » 2011-11-22 22:08

Hello guys;
Well i don't want to become an NDR attack target, but i don't wanna penalize good people sending emails and making errors in the address or the recepient mailbox is full. How to go about this?
My hmailserver is sitting in between Internet and backend exchange servers.
please share your experiences with me.
Thanks.

Incorrect addresses don't cause NDRs on their own

If users don't have a limit on storage space then mailbox can never be full. (No NDRs)
Other cause of NDRs could be auto-replies.
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

Thanks Mattg, but i dosagree with you.
1. Incorrect addresses in my case will cause NDRs sent out by hmailserver (frontend for backend exchange)
2. We're not as big as gmail to give 10GB mailboxes.
