DNS that is used by postfix stopped working and consequently caused postfix
respond to:1. senders from outside: NOQUEUE: reject: RCPT from
unknown[194.168.1.66]: 450 4.1.82. senders from inside (LAN): NOQUEUE: reject:
RCPT from unknown[172.16.125.115]: 450 4.1.2
1. case looks Ok, mailservers from outside keep trying to deliver the rejected
messages.2. case is not that good. Email clients on LAN e.g. outlook generate
failed delivery message 450 4.1.2. The problem is that I use AVG antivirus
to check emails and it will not generate any message in this case. In case of
DNS failure, can I configure postfix to construct standard message (failed
delivery) for senders from LAN (local users of postfix server) andfor senders
from outside (other email servers) to keep responding 450 4.1.8?
Thank you,Peter
