I'd like to confirm the meaining of a mail failure notice. Here's the message
Hi. This is the qmail-send program at mydomain.com I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <email@example.com>: 220.127.116.11 does not like recipient. Remote host said: 554 <firstname.lastname@example.org>: Relay access denied Giving up on 18.104.22.168
The way I understand this is, that 22.214.171.124 is not setup to receive mail for this domain.
dig domain.com MX shows
;; ANSWER SECTION: domain.com. 6245 IN MX 10 mail.domain.com. domain.com. 6245 IN MX 20 mx.anotherdomain.com.
(126.96.36.199 is mx.anotherdomain.com.).
The puzzling part is that I have reports that messages sent from gmail get delivered to this address.
P.S. Is this a proper question for serverfault?
