To configure rainloop, use admin panel found at : https://webmail.domain.tld/?admin

💡 Don't forget to add a new A/CNAME record in your DNS zone.

Default login is "admin", password is "12345".

You must add and configure your domains in your admin panel like this :

# docker logs -f rainloop

nginx: [alert] could not open error log file: open() "/var/lib/nginx/logs/error.log" failed (13: Permission denied)

This issue can append with some specific file systems. If that happens, use nginx user inside the container :

rainloop:
  environment:
    - UID=nginx
    - GID=nginx
