# The mailman object is used for receiving (POP3) 
# and sending (SMTP) email.
$mailman = chilkat::CkMailMan->new();

# To connect through an HTTP proxy, set the HttpProxyHostname
# and HttpProxyPort properties to the hostname (or IP address)
# and port of the HTTP proxy.  Typical port numbers used by
# HTTP proxy servers are 3128 and 8080.
$mailman->put_HttpProxyHostname("www.my-http-proxy.com");
$mailman->put_HttpProxyPort(3128);

# Important:  Your HTTP proxy server must allow non-HTTP
# traffic to pass.  Otherwise this does not work.

# Set the POP3 server's hostname
$mailman->put_MailHost("pop.example.com");

# Set the POP3 login/password.
$mailman->put_PopUsername("myLogin");
$mailman->put_PopPassword("myPassword");

# Copy the all email from the user's POP3 mailbox 
# into a bundle object.  The email remains on the server.
# 
# NOTE: All methods that communicate with a POP3 server
# will automatically connect and authenticate (i.e. login)
# if not already connected.  The connection will remain
# open after the method call returns so that subsequent
# calls do not need to re-establish the connection.
# In this case, the connection is established via the HTTP
# proxy.
