Error message

the recipient has unsubscribed from the current group and cannot send

What it means

rebuildPostfixServiceNetworks1 (the second, type-checked rebuild variant) requires the parsed docker-compose config to expose a top-level 'services' mapping. It throws this error when dockerConfig lacks the key or it is not map[string]interface{}, indicating the file is not a recognizable docker-compose document.

Solutions

1. Check the compose file has a top-level 'services:' mapping with correct indentation
2. Re-validate/re-parse the YAML and inspect the resulting map before calling the rebuild
3. Point the ConfigManager at the correct docker-compose.yml
4. Restore the stock BillionMail docker-compose.yml

Example fix

# before
networks:
  billionmail-network: {}
# after
services:
  postfix-billionmail:
    image: billionmail/postfix
networks:
  billionmail-network: {}

if svc, ok := dockerConfig["services"]; !ok || svc == nil {
	return fmt.Errorf("docker-compose.yml missing services section")
}

func isValidComposeDoc(cfg map[string]interface{}) bool {
	_, ok := cfg["services"].(map[string]interface{})
	return ok
}

if err := m.rebuildPostfixServiceNetworks1(dockerConfig, configs); err != nil {
	if strings.Contains(err.Error(), "missing 'services' section") {
		// re-read / repair the file and re-parse before retrying
	}
	return err
}

When it happens

Trigger: Calling rebuildPostfixServiceNetworks1 with a config from a YAML file missing 'services:', an empty file, or YAML where 'services' decodes to a non-map value (nil, array).

Common situations: Corrupted or truncated docker-compose.yml after a failed edit; passing a partial config; pointing the manager at the wrong YAML file (e.g. an env file).
