Are you sure the word "exception" is there? Postfix does not generate

does that domain have A record?

Now, when I try to use the server to send real mails (from outside to local

Turn off the default safety net, I have:
unknown_address_reject_code = 550
unknown_client_reject_code = 550
unknown_hostname_reject_code =

found
What seems reasonable to me is the following:

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

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:

What seems reasonable to me is
OK
I have run postmap and reloaded postfix and yet we still see this error

Start by making sure that these match:
/etc/resolv.conf
/var/spool/postfix/etc/resolv.conf
Yup. Postfix start warns me if they differ.
I tried putting in nameservers there, but that makes it worse: then postfix
(it's supposed to relay) accepts the messages, then can't find te relay d

Start by making sure that these match:
/etc/resolv.conf
/var/spool/postfix/etc/resolv.conf

fsvo "correct". When postfix can't resolve dns, it usu
not found, try again
and, on every message coming in, rejection:
postfix/smtpd[5916]: NOQUEUE: reject: RCPT from unknown[65.55.90.236]: 450
