# IMC
|
|
|
|
A self-sufficient web application to manage an ISPmail (Postfix, Dovecot, Rspamd) mail server.
|
|
|
|
## Features
|
|
|
|
- **Domain Management** - Add, view, and delete mail domains
|
|
- **User Management** - Create and manage mail users per domain
|
|
- **Alias Management** - Create and manage email aliases per domain
|
|
- **Mail Queue** - View, requeue, and delete queued emails
|
|
- **Mail Logs** - View postfix logs with filtering
|
|
- **Password Management** - Change password for admin users
|
|
|
|
## Tech Stack
|
|
|
|
- **Backend**: Go with Gin framework, GORM for database
|
|
- **Frontend**: SvelteKit
|
|
- **Database**: MariaDB/MySQL (shared with mail server ISPmail schema)
|
|
- **Auth**: JWT-based authentication
|
|
|
|
## Architecture
|
|
|
|
- Single binary with embedded frontend (no separate web server needed)
|
|
- All database tables use `imc_` prefix to avoid conflicts with ISPmail schema
|
|
- Permissions controlled via `imc_users2domains` table
|
|
- Admin users have access to all domains; non-admin users only to assigned domains
|
|
|

|
## Quick Start
|
|
|
|
### 1. Build
|
|
|
|
```bash
|
|
make build
|
|
```
|
|
|
|
### 2. Create Admin User
|
|
|
|
```bash
|
|
./build/imc --reset-admin-password
|
|
# This creates an admin user or resets the password
|
|
# Output: Username: admin, Password: (randomly generated)
|
|
```
|
|
|
|
### 3. Run
|
|
|
|
```bash
|
|
./build/imc --bind=0.0.0.0 --port=8080
|
|
```
|
|
|
|
### 4. Access
|
|
|
|
Open `http://your-server:8080` and login with the admin credentials.
|
|
|
|
## Configuration
|
|
|
|
### Environment Variables
|
|
|
|
| Variable | Description | Default |
|
|
|----------|-------------|---------|
|
|
| `DB_HOST` | Database host | `localhost` |
|
|
| `DB_PORT` | Database port | `3306` |
|
|
| `DB_USER` | Database user | `mailadmin` |
|
|
| `DB_PASSWORD` | Database password | (required) |
|
|
| `DB_NAME` | Database name | `mailserver` |
|
|
| `BIND` | IP to bind to | `0.0.0.0` |
|
|
| `PORT` | Port to listen on | `8080` |
|
|
| `JWT_SECRET` | JWT signing secret (min 32 chars) | (required) |
|
|
|
|
### CLI Flags
|
|
|
|
```bash
|
|
./imc --help
|
|
```
|
|
|
|
```
|
|
-bind string
|
|
IP address to bind to (default: 0.0.0.0)
|
|
-port string
|
|
Port to listen on (default: 8080)
|
|
-reset-admin-password
|
|
Reset admin password to a random value and exit
|
|
```
|
|
|
|
## Database Tables
|
|
|
|
The app creates these tables automatically:
|
|
|
|
- `imc_users` - App admin users
|
|
- `imc_login_attempts` - Brute force protection
|
|
- `imc_users2domains` - User-domain permissions
|
|
|
|
Existing ISPmail tables (`virtual_domains`, `virtual_users`, `virtual_aliases`) are used for mail data.
|
|
|
|
## Systemd Service
|
|
|
|
Example service file at `/etc/systemd/system/imc.service`:
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=IMC Mail Admin
|
|
After=network.target mariadb.service postfix.service
|
|
|

|
## Requirements
|
|
|
|
- Go 1.21+
|
|
- Bun (for frontend development)
|
|
- MariaDB/MySQL
|
|
- Postfix (with postqueue/postsuper)
|
|
- systemd-journald (for log viewing)
|
|
|
|
## Development
|
|
|
|
Run development server that watches for file changes:
|
|
|
|
```sh
|
|
make dev
|
|
```
|
|
|
|
Build the binary into the build/ directory:
|
|
|
|
```bash
|
|
# Build frontend and backend
|
|
make build
|
|
```
|
|
|
|
Build only frontend or backend:
|
|
|
|
```sh
|
|
# Run backend only (uses filesystem frontend)
|
|
cd backend && go run ./cmd/server
|
|
|
|
# Run frontend dev server
|
|
cd frontend && bun run dev
|
|
```
