## Features

- Connect and disconnect from an IMAP server
- List messages in a specified mailbox
- Export messages to various formats
- Manage multiple users with separate IMAP clients

## Installation

To install the package, use `go get`:

```bash
go get git.b0zal.io/H0llyW00dzZ/imap
```

## Usage

### Single User

```go
package main

import (
	"fmt"
	"log"

	"git.b0zal.io/H0llyW00dzZ/imap/client"
)

func main() {
	config := &client.Config{
		Username:           "user@example.com",
		Password:           "password",
		Server:             "imap.example.com:993",
		InsecureSkipVerify: true,
	}

	imapClient := client.NewIMAP(config)

	err := imapClient.Connect()
	if err != nil {
		log.Fatalf("Failed to connect: %v", err)
	}
	defer imapClient.Disconnect()

	messageConfig := client.MessageConfig{
		GrabID:      true,
		GrabFrom:    true,
		GrabSubject: true,
		GrabBody:    true,
	}

	messages, err := imapClient.ListMessages("INBOX", 10, messageConfig)
	if err != nil {
		log.Fatalf("Failed to list messages: %v", err)
	}

	for _, msg := range messages {
		fmt.Printf("ID: %s, From: %v, Subject: %s, Body: %s\n", msg[client.KeyID], msg[client.KeyFrom], msg[client.KeySubject], msg[client.KeyBody])
	}
}
```

### Multiple Users

```go
package main

import (
	"fmt"
	"log"

	"git.b0zal.io/H0llyW00dzZ/imap/client"
)

func main() {
	multiUserIMAP := client.NewMultiUserIMAP()

	multiUserIMAP.AddUser("user1@example.com", "password1", "imap.example.com:993", true)
	multiUserIMAP.AddUser("user2@example.com", "password2", "imap.example.com:993", true)

	err := multiUserIMAP.ConnectUser("user1@example.com")
	if err != nil {
		log.Fatalf("Failed to connect user1: %v", err)
	}
	defer multiUserIMAP.DisconnectUser("user1@example.com")

	messageConfig := client.MessageConfig{
		GrabID:      true,
		GrabFrom:    true,
		GrabSubject: true,
		GrabBody:    true,
	}

	messages, err := multiUserIMAP.ListUserMessages("user1@example.com", "INBOX", 10, messageConfig)
	if err != nil {
		log.Fatalf("Failed to list messages for user1: %v", err)
	}

	for _, msg := range messages {
		fmt.Printf("ID: %s, From: %v, Subject: %s, Body: %s\n", msg[client.KeyID], msg[client.KeyFrom], msg[client.KeySubject], msg[client.KeyBody])
	}
}
```

### Exporting Messages

```go
package main

import (
	"log"
	"os"

	"git.b0zal.io/H0llyW00dzZ/imap/client"
	"git.b0zal.io/H0llyW00dzZ/imap/export"
)

func main() {
	config := &client.Config{
		Username:           "user@example.com",
		Password:           "password",
		Server:             "imap.example.com:993",
		InsecureSkipVerify: true,
	}

	imapClient := client.NewIMAP(config)

	err := imapClient.Connect()
	if err != nil {
		log.Fatalf("Failed to connect: %v", err)
	}
	defer imapClient.Disconnect()

	messageConfig := client.MessageConfig{
		GrabID:      true,
		GrabFrom:    true,
		GrabSubject: true,
		GrabBody:    true,
	}

	file, err := os.Create("messages.json")
	if err != nil {
		log.Fatalf("Failed to create file: %v", err)
	}
	defer file.Close()

	exporter := &export.JSONExporter{Encoder: export.DefaultJSONEncoder}
	err = imapClient.ExportMessagesTo(file, exporter, "INBOX", 10, messageConfig)
	if err != nil {
		log.Fatalf("Failed to export messages: %v", err)
	}
}
```
