Hello,
I have a question about how Postfix generate warning messages about
non-existent domains, non-existent MX domain names or for timeout
connecting to a destination mail server. In fact, my real problem is
that postfix does not warn me about nothing when I incorrectly write the
domain name for an email address AND by chance that domain exists but
does not have configured MX record on its DNS.
For example for a non-existent domain I receive almost instantly the
message /"t...@asdasdasd.ro <mailto:t...@asdasdasd.ro>: Host or domain
name not found. Name service error for name=asdasdasd.ro type=A: Host
not found"/
For an existing domain but without MX, I receive the error /"Host or
domain name not found. Name service error for name=onedomain.com
type=MX: Host not found, try again)"/, but AFTER
/maximal_queue_lifetime/, which is very annoying. In this case the
sender finds out only after 5 days about the real problem.
Is there any way to modify postfix configuration to inform the sender
about such a problem instantly and to retry to send message until
/maximal_queue_lifetime/ expires?
Thank you for your time.
Best regards,
Catalin
