Hi everyone,
I’m running mailcow dockerized 2024-04 on Ubuntu 20.4 VM since years. When setting up the server I followed the steps to disable IPv6. I reverted the changes after getting the Error “Execution of Sieve filters was aborted due to temporary failure (in reply to end of DATA command)” when enabling a forwarding of E-Mail account in Sogo for the first time. Forwarding now is functional, but after “docker-compose up -d” I’m getting still the e-mail from watchdog@mymailcowserver saying “enable_ipv6 is true in docker-compose.yml, but an IPv6 link could not be established. Please verify your IPv6 connection”.
I checked all settings from the site “https://docs.mailcow.email/post_installation/firststeps-disable_ipv6/”, but did not find a clue. Firewall on Ubuntu server is disabled. How can I find out what is still causing the message?
Thanks in advance.
Best regards, vmt
