With Gogs' ability to authenticate over SMTP it is trivial to integrate it with mailcow. Few changes are needed:

1. Open docker-compose.override.yml and add Gogs:

version: '2.1'
services:

    gogs-mailcow:
      image: gogs/gogs
      volumes:
        - ./data/gogs:/data
      networks:
        mailcow-network:
          aliases:
            - gogs
      ports:
        - "${GOGS_SSH_PORT:-127.0.0.1:4000}:22"

2. Create data/conf/nginx/site.gogs.custom, add:

location /gogs/ {
    proxy_pass http://gogs:3000/;
}

3. Open mailcow.conf and define the binding you want Gogs to use for SSH. Example:

GOGS_SSH_PORT=127.0.0.1:4000

5. Run the commands to bring up the Gogs container and restart the nginx-mailcow container afterwards:

=== "docker compose (Plugin)"

``` bash
docker compose up -d
docker compose restart nginx-mailcow
```

=== "docker-compose (Standalone)"

``` bash
docker-compose up -d
docker-compose restart nginx-mailcow
```

6. Open http://${MAILCOW_HOSTNAME}/gogs/, for example http://mx.example.org/gogs/. For database details set mysql as database host. Use the value of DBNAME found in mailcow.conf as database name, DBUSER as database user and DBPASS as database password.

7. Once the installation is complete, login as admin and set "settings" -> "authorization" -> "enable SMTP". SMTP Host should be postfix with port 587, set Skip TLS Verify as we are using an unlisted SAN ("postfix" is most likely not part of your certificate).

8. Create data/gogs/gogs/conf/app.ini and set following values. You can consult Gogs cheat sheet for their meaning and other possible values.

[server]
SSH_LISTEN_PORT = 22
# For GOGS_SSH_PORT=127.0.0.1:4000 in mailcow.conf, set:
SSH_DOMAIN = 127.0.0.1
SSH_PORT = 4000
# For MAILCOW_HOSTNAME=mx.example.org in mailcow.conf (and default ports for HTTPS), set:
ROOT_URL = https://mx.example.org/gogs/

9. Restart Gogs with the following command. Your users should be able to login with mailcow managed accounts.

=== "docker compose (Plugin)"

``` bash
docker compose restart gogs-mailcow
```

=== "docker-compose (Standalone)"

``` bash
docker-compose restart gogs-mailcow
```
