Hi list!
Yesterday I was experimenting with the DNS registries assigned to my mail
server.
Currently I have this configuration:
;; ANSWER SECTION:
devels.es. 13325 IN A 91.215.158.237
;; ANSWER SECTION:
devels.es. 14400 IN MX 0 mail.devels.es.
;; ADDITIONAL SECTION:
mail.devels.es. 14400 IN A 85.155.102.33
91.215.158.237 is the IP of my registrar, so it's not the IP of the maching
having the Postfix server. 85.155.102.33 is Postfix server machine's IP.
This config actually work; I can send/receive mails without any problem.
But yesterday I changed this registry:
devels.es. 13325 IN A 91.215.158.237
To:
devels.es. 13325 IN A 85.155.102.33
So the A record would point to my machine too, and I started to get this
message each time I wanted to send/receive a mail:
Oct 1 22:37:00 mail postfix/smtp[1850]: D01AD101534: to=<
todos.somos...@gmail.com>, relay=devels.es[85.155.102.33]:25, delay=0.35,
delays=0.14/0.06/0.15/0, dsn=5.4.6, status=bounced (mail for [devels.es]
loops back to myself)
It's true that devels.es is not among 'mydestination', but as I'm using
virtual mailboxes, it's listed in virtual_mailbox_domains, so I can't add
it in both places. The questions are,
1) Why is this happening if I change that registry?
2) What would I need to change in my config to make this work if I want to
change that DNS registry?
Below is my postconf -n.
