An interface to get emails via the imap protocol (version 4rev1)

This interface implements the IMAP protocol (version 4 rev 1) as described in rfc 3501. This package gives an easy access to all commands and automatically analyzes responses. All responses are accessible through an ImapResponse object.

Supported extensions:

  • RFC 2177: IMAP4 IDLE command

This package is made available under the GNU General Public License v3.0.


This example connects the client to an imap server:

import 'package:imap_client/imap_client.dart';

main() async {
  ImapClient client = new ImapClient();
  await client.connect("", 993, true).then((response) {

All commands are async methods that can be awaited for. On completion, they return an ImapResponse object, which holds all data that was returned by the server until command completion. It also holds the command completion status:

  • OK: success
  • NO: command was unsuccessful
  • BAD: command not accepted by the server

Update responses are handled as soon as they arrive and don't show up in the ImapResponse. To get EXISTS responses, you must supply a handler function, that takes care of it. Other update responses are: EXPUNGE, RECENT, FETCH and ALERT. Handlers can be set by setting the client's typeHandler attributes.

Example for EXISTS:

client.existsHandler = (String mailboxName, int messageNumber) { ... }
