Save Email Attachments to Disk

Example source code to save email attachments to disk.

// The Chilkat Email library is also available as an ActiveX component
// or .NET class with the identical set of methods and properties.

// C++ showing how to save attachments to disk.

    // mailman.put_MailPort(995);
    // Tell the mailman to connect to POP3 using SSL
    // mailman.put_PopSsl(true);
