Extract Emails

GroupDocs.Parser provides the functionality to extract emails from remote servers. The following email protocols are supported:

Post Office Protocol (POP)
Internet Message Access Protocol (IMAP)
Exchange Web Services (EWS)

To create an instance of Parser class to extract emails from a remote server the following constructor is used:

Parser(String filePath, LoadOptions loadOptions);

Here are the steps to extract emails from the remote server:

Prepare connection string (see table below);
Instantiate *Parser *object with connection string;
Call *getFeatures().isContainer() *property to check if container extraction is supported;
Call getContainer method and obtain collection of document container item objects;
Iterate through the collection and get Parser object for each item.

The following example shows how to extract emails from Exchange Server:

StringBuilder sb = new StringBuilder();
sb.append("mode = exchange");
sb.append('\n');
sb.append("MailboxUri = https://outlook.office365.com/ews/exchange.asmx");
sb.append('\n');
sb.append("Username = email@server");
sb.append('\n');
sb.append("Password = password");
// Create an instance of Parser class to extract emails from the remote server
// As filePath connection parameters are passed; LoadOptions is set to Email file format
try (Parser parser = new Parser(sb.toString(), new LoadOptions(FileFormat.Email))) {
    // Check if container extraction is supported
    if (!parser.getFeatures().isContainer()) {
        System.out.println("Container extraction isn't supported.");
        return;
    }
    // Extract email messages from the server
    Iterable<ContainerItem> emails = parser.getContainer();
    // Iterate over attachments
    for (ContainerItem item : emails) {
        // Create an instance of Parser class for email message
        try (Parser emailParser = item.openParser()) {
            // Extract the email text
            try (TextReader reader = emailParser.getText()) {
                // Print the email text
                System.out.println(reader == null ? "Text extraction isn't supported." : reader.readToEnd());
            }
        }
    }
}

The following connection parameters are used:

POP	mode = pop

| | IMAP | mode = imap
Host =
