IMAP, POP3 and SMTP email clients in pure Dart. Choose between a low level and a high level API for mailing.

More...

Experimental IMAP, POP3 and SMTP clients for Dart developers.

Available under the commercial friendly MPL Mozilla Public License 2.0.

Warning: Incoming Changes to v0.0.x API #

I will change the API to use exceptions rather than Response objects, before increasing the version of this package to 0.1.0. This will ease the usage in the happy sunshine cases drastically. Also compare https://github.com/Enough-Software/enough_mail/issues/101. Thanks for testing enough_mail!

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) {
    print(mailboxesResponse.result);
    await mailClient.selectInbox();
    var fetchResponse = await mailClient.fetchMessages(count: 20);
    if (fetchResponse.isOkStatus) {
      for (var msg in fetchResponse.result) {
        printMessage(msg);
      }
    }
  }
  mailClient.eventBus.on<MailLoadEvent>().listen((event) {
    print('New message at ${DateTime.now()}:');
    printMessage(event.message);
  });
  mailClient.startPolling();
}

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();
  exit(0);
}

Future<void> discoverExample() async {
  var email = 'someone@enough.de';
  var config = await Discover.discover(email, isLogEnabled: false);
  if (config == null) {
    print('Unable to discover settings for $email');
  } else {
    print('Settings for $email:');
    for (var provider in config.emailProviders) {
      print('provider: ${provider.displayName}');
      print('provider-domains: ${provider.domains}');
      print('documentation-url: ${provider.documentationUrl}');
      print('Incoming:');
      print(provider.preferredIncomingServer);
      print('Outgoing:');
      print(provider.preferredOutgoingServer);
    }
  }
}

Future<void> imapExample() async {
  var client = ImapClient(isLogEnabled: false);
  await client.connectToServer(imapServerHost, imapServerPort,
      isSecure: isImapServerSecure);
  var loginResponse = await client.login(userName, password);
  if (loginResponse.isOkStatus) {
    var listResponse = await client.listMailboxes();
    if (listResponse.isOkStatus) {
      print('mailboxes: ${listResponse.result}');
    }
    var inboxResponse = await client.selectInbox();
    if (inboxResponse.isOkStatus) {
      // fetch 10 most recent messages:
      var fetchResponse = await client.fetchRecentMessages(
          messageCount: 10, criteria: 'BODY.PEEK[]');
      if (fetchResponse.isOkStatus) {
        var messages = fetchResponse.result.messages;
        for (var message in messages) {

      isSecure: isSmtpServerSecure);
  var ehloResponse = await client.ehlo();
  if (!ehloResponse.isOkStatus) {
    print('SMTP: unable to say helo/ehlo: ${ehloResponse.message}');
    return;
  }

  if (loginResponse.isOkStatus) {
    var builder = MessageBuilder.prepareMultipartAlternativeMessage();
    builder.from = [MailAddress('My name', 'sender@domain.com')];
    builder.to = [MailAddress('Your name', 'recipient@domain.com')];
    builder.subject = 'My first message';
    builder.addTextPlain('hello world.');
    builder.addTextHtml('<p>hello <b>world</b></p>');

      print(
          'status: messages count=${statusResponse.result.numberOfMessages}, messages size=${statusResponse.result.totalSizeInBytes}');
