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
