I have a question about the situation where postfix receives a connection
from a client trying to send to an invalid recipient address such as
u...@nohow.noway.org.
Currently, postfix responds with:
450 4.1.2 u...@nohow.noway.org: Recipient address rejected: Domain not
found
What seems
rejected: Domain not
found
What seems reasonable to me is the following:
-- If postfix receives a response from DNS that the domain does not
exist, then reject with 550
-- Otherwise, delay with 450 (DNS failure, etc.)
nonsense - your own incoming server don't need to depend on DNS to guess
