I want to send a "could not be delivered" message only to email@??? when the domain part of the recipient is wrong (I dont want to return a "could not be delivered" message to the sender).
In config - dnslookup: router I have errors_to=email@???
This work out when the mailbox part of the recipient is wrong (but the domain is correct). But how I send a message to email@??? when the domain part of the recipient is wrong too?
