Add native cmd:// support in Mailrise Docker image

[geotibi]

Currently, the Mailrise Docker image cannot use cmd:// URLs for executing local scripts, which prevents sending SMS through custom scripts.

I have a local sms gateway that I want to use but i cannot use into configuration something like

configs:
  sms:
    urls:
      - cmd:///etc/script.sh

When call the script in the logs of container I can see cmd://etc/script.sh, so the triple slash is translated to double slash and the script is not executed. Another option is to use a curl command instead of my script, similar like from postman

postman request POST '192.168.1.30:8080/message' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Basic gdfhvtrvryuvvtu' \
  --body '{
    "textMessage": {
        "text": "Hello!"
    },
    "phoneNumbers": [
        "+123456789"
    ]
}' \
  --auth-basic-username 'user' \
  --auth-basic-password 'pass'

Can I do this? I've searched into documentation but still cannot make this running
