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 protected]>:
1.2.3.4 does not like recipient.
Remote host said: 554 <[email protected]>: Relay access denied
Giving up on 1.2.3.4
The way I understand this is, that 1.2.3.4 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.
(1.2.3.4 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?
It means to deliver the mail 1.2.3.4 would have to pass it on to another mailserver (because 1.2.3.4 is not the final destination) and it does not want to do that.
