Deleting Messages from Server

Deleting Messages

The ImapClient class can delete messages from an IMAP server. The ImapClient class deleteMessage() function is used to delete messages. It takes the message sequence number or unique ID as a parameter. The ImapClient provides deleteMessage and deleteMessages methods for deleting messages one by one or multiple. The following code snippet shows you how to delete an email message with the message ID 1 from an IMAP server.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
final ImapClient client = new ImapClient("exchange.aspose.com", "username", "password");
try {
    try {
        System.out.println(client.getUidPlusSupported());
        // Append some test messages
        client.selectFolder(ImapFolderInfo.IN_BOX);
        MailMessage message = new MailMessage("[e-mail]", "[e-mail]", "EMAILNET-35227 - " + UUID.randomUUID(),
                "EMAILNET-35227 Add ability in ImapClient to delete message");
        String emailId = client.appendMessage(message);

        // Now verify that all the messages have been appended to the mailbox
        ImapMessageInfoCollection messageInfoCol = null;
        messageInfoCol = client.listMessages();
        System.out.println(messageInfoCol.size());

        // Select the inbox folder and Delete message
        client.selectFolder(ImapFolderInfo.IN_BOX);
        client.deleteMessage(emailId);
        client.commitDeletes();
    } finally {

    }
} finally {
    if (client != null)
        client.dispose();
}

Deleting Multiple Messages

Multiple emails can be deleted from mailbox using the ImapClient of Aspose.Email API. The deleteMessages method provides a number of options to delete multiple messages from the server using unique ids, sequence numbers or ImapMessageInfoCollection elements. The following code snippet shows you how to delete multiple messages.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
final ImapClient client = new ImapClient("exchange.aspose.com", "username", "password");
try {
    try {
        System.out.println(client.getUidPlusSupported());
        // Append some test messages
        client.selectFolder(ImapFolderInfo.IN_BOX);
        List<String> uidList = new ArrayList<String>();
        final int messageNumber = 5;
        for (int i = 0; i < messageNumber; i++) {
            MailMessage message = new MailMessage("[e-mail]", "[e-mail]", "EMAILNET-35226 - " + UUID.randomUUID(),
                    "EMAILNET-35226 Add ability in ImapClient to delete messages and change flags for set of messages");
            String uid = client.appendMessage(message);
            uidList.add(uid);
        }

        // Now verify that all the messages have been appended to the mailbox
        ImapMessageInfoCollection messageInfoCol = null;
        messageInfoCol = client.listMessages();
        System.out.println(messageInfoCol.size());

        // Bulk Delete Messages and Verify that the messages are deleted
        client.deleteMessagesByUids(uidList, true);
        client.commitDeletes();
        messageInfoCol = null;
        messageInfoCol = client.listMessages();
        System.out.println(messageInfoCol.size());
    } finally {

    }
} finally {
    if (client != null)
        client.dispose();
}
