High Level API Usage #

A simple usage example for using the high level API:

import 'dart:io';
import 'package:enough_mail/enough_mail.dart';

String userName = 'user.name';
String password = 'password';

void main() async {
  await mailExample();

Future<void> mailExample() async {
  var email = userName + '@domain.com';
  var config = await Discover.discover(email);
  var account =
      MailAccount.fromDiscoveredSetings('my account', email, password, config);
  var mailClient = MailClient(account, isLogEnabled: true);
  await mailClient.connect();
  var mailboxesResponse =
      await mailClient.listMailboxesAsTree(createIntermediate: false);
  if (mailboxesResponse.isOkStatus) {
    await mailClient.selectInbox();
    var fetchResponse = await mailClient.fetchMessages(count: 20);
    if (fetchResponse.isOkStatus) {
      for (var msg in fetchResponse.result) {
  mailClient.eventBus.on<MailLoadEvent>().listen((event) {
    print('New message at ${DateTime.now()}:');

Low Level Usage #

A simple usage example for using the low level API:

import 'dart:io';
import 'package:enough_mail/enough_mail.dart';

String userName = 'user.name';
String password = 'password';
String imapServerHost = 'imap.domain.com';
int imapServerPort = 993;
bool isImapServerSecure = true;
String popServerHost = 'pop.domain.com';
int popServerPort = 995;
bool isPopServerSecure = true;
String smtpServerHost = 'smtp.domain.com';
int smtpServerPort = 465;
bool isSmtpServerSecure = true;

void main() async {
  await discoverExample();
  await imapExample();
  await smtpExample();
  await popExample();

Future<void> discoverExample() async {
  var email = 'someone@enough.de';

          messageCount: 10, criteria: 'BODY.PEEK[]');
      if (fetchResponse.isOkStatus) {
        var messages = fetchResponse.result.messages;
        for (var message in messages) {

    var sendResponse = await client.sendMessage(mimeMessage);
    print('message sent: ${sendResponse.isOkStatus}');

Future<void> popExample() async {
  var client = PopClient(isLogEnabled: false);
  await client.connectToServer(popServerHost, popServerPort,
      isSecure: isPopServerSecure);
  var loginResponse = await client.login(userName, password);

          await client.retrieve(statusResponse.result.numberOfMessages + 1);
          'trying to retrieve newer message succeeded: ${retrieveResponse.isOkStatus}');
  await client.quit();

void printMessage(MimeMessage message) {
  print('from: ${message.from} with subject "${message.decodeSubject()}"');
  if (!message.isTextPlainMessage()) {
    print(' content-type: ${message.mediaType}');
