erm, people who email ciefexec@mydomain.com instead of chiefexec@mydomain.com wouldnt get a NDR and could argue until they are blue in the face that they DID infact sent the highly important contract before the deadline expired
In theory though it will sit in your badmail folder and you would be able to prove that it wouldnt have arrived anyway due to incorrect addressing.
Might be worth waiting for some additional input from some other forum members, as I'm sure my input isnt the be-all and end-all on the subject ;-)
