ok. Nu stiam cum e cu unbound. Am mai invatat ceva , multumesc!
dar am pus la containerul postfix dns: 1.1.1.1 si 8.8.8.8 in resolv.conf
a ramas 127.0.0.11 dar acum rezolva hidroelectrica.ro in container .
Presupun ca face redirectarea care o facea catre unbound catre 1.1.1.1
root@mail:/home/paul/mailcow/mailcow-dockerized# docker exec -it
mailcowdockerized-postfix-mailcow-1 nslookup mail.hidroelectrica.ro
Server: 127.0.0.11
Address: 127.0.0.11#53
Non-authoritative answer:
Name: mail.hidroelectrica.ro
Address: 91.216.144.232
Name: mail.hidroelectrica.ro
Address: 91.216.144.231
acum cred insa ca e ceva buba si cu DNS hidroelectrica de nu il rezolva
multi inclusiv unbound
de ex :
root@mail:/home/paul/mailcow/mailcow-dockerized# dig mx hidroelectrica.ro

Multumesc, acum mi-a dat la hidroelectrica doar greylisted sper ca mai
apoi sa primeasca mailuri

La docker (docker-compose0 poti sa speicific ce DNS servere vrei tu:
https://github.com/compose-spec/compose-spec/blob/master/spec.md#dns
m-am uitat rapid la docker-compose.yml de la mailcow si din ce vad
foloseste unbound pentru DNS cu toate celelalte containere folosind
serviciul respectiv (am decupat ce nu era relevant):
unbound-mailcow:
image: mailcow/unbound:1.17
networks:
mailcow-network:
ipv4_address: ${IPV4_NETWORK:-172.22.1}.254
aliases:
- unbound
postfix-mailcow:
image: mailcow/postfix:1.71
dns:
- ${IPV4_NETWORK:-172.22.1}.254
networks:
mailcow-network:
ipv4_address: ${IPV4_NETWORK:-172.22.1}.253
aliases:
- postfix
daca la tine resolv.conf apare cu 127.0.0.11 inseamna ca ai ceva
mailcow mai vechi ? dar solutia e aceeasi, pune
dns:
- 1.1.1.1
- 8.8.8.8
la postfix (sau la toate) si ai rezolvat

din pacate nu stiu de unde isi ia forwarders
