// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The mailman object is used for receiving (POP3) 
// and sending (SMTP) email.

// Set the POP3 server's hostname
mailman.MailHost = @"pop.example.com";

// Set the POP3 login/password.

// First, get the complete set of UIDLs for the email in the POP3 mailbox:

success = [mailman FetchUidls: stUidls];
if (success == NO) {

// Download each email as MIME.
// If desired, the MIME can be loaded into an email object.
