Now they want our postfix server to accept all mails without checks and
send NDR's for undeliverable mails.
Even if you can make this work, it's still a bad idea, since the
outbound SMTP server will be blacklisted for sending to too many invalid
addresses. Because it ignores bounces, the mailing list will never be
updated to remove invalid recipients.
