I recently disabled ipv6 on my mailcow server using this guide (https://docs.mailcow.email/post_installation/firststeps-disable_ipv6/), and it seemed to work fine, but now I want to undo my changes and re-enable ipv6.
I’m pretty confident I could undo the changes I made to the conf and yml files from steps 1-4 of this guide, but step 5 was to run the “sed” command and change a bunch of conf files blindly.
Does anyone know where I could find originals of these files to replace the sedded ones, and is this the safest way to achieve my goal?
Thanks.
