It has *no local authentication configured* and is supposed to run in a trusted environment.\n\n# Environment Variables\n\nThe entry point requires the following environment variables:\n  * `SERVER_HOSTNAME`: the hostname for this container;\n  * `SMTP_SERVER`: the address of the SMTP server to use.\n\nThe following environment variables are optional:\n  * `SMTP_PORT` (defaults to 587): the port of the target SMTP server (used together with `SERVER_HOSTNAME`);\n  * `SMTP_USERNAME`: the username to authenticate with. If it is not empty, then it is mandatory to pass one of `SMTP_PASSWORD` or `SMTP_PASSWORD_FILE`;\n  * `SMTP_PASSWORD_FILE`: the file containing the password of the authenticating user. The entry point script will read this file and assign its contents to the `SMTP_PASSWORD` variable;\n  * `SMTP_PASSWORD`: the password of the authenticating user;\n  * `SMTP_NETWORKS` (defaults to `10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16`): the list of networks that are allowed to relay emails via this server; \n  * `DEBUG`: set to `yes` to enable debugging (effectively executes `set -x`).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsjinks%2Fdocker-alpine-postfix-relay","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsjinks%2Fdocker-alpine-postfix-relay","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsjinks%2Fdocker-alpine-postfix-relay/lists"}
