I've been using it for last year or so, so decided to release it publicly.\n\n## Warning\n\nIf configured incorrectly, this can become an open relay SMTP server, so hosting it on public interfaces is not advisable.\n\n## Why\n\nIf you have devices which can send notifications, but does not support SMTP authentication, or SMTP authentication is broken -- relay SMTP server can help. It will relay via upstream SMTP server. `Received` header will be hidden, so your internal network information won't leak.\n\n## Usage\n\nModify `docker-compose.yml` with your settings. Then:\n\n```sh\ndocker compose up -d\n```\n\nConfigure email client to send email via your local SMTP server.\n\n## SSL\n\nRequest SSL certificate from [Let's Encrypt][1] using [lego][2] or any other tool, and save certificate as `cert.pem` and private key as `key.pem` in the root of the repository.\n\n## Thanks\n\nSome ideas where found and sometimes copied from the following projects:\n\n* [Headers check][3] and [mail-in-a-box][4]\n* [runit][5]\n* [mail-in-a-box][4]\n\n## Bug reports and pull requests\n\nThis is open source project.
