# 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.
mailman = Chilkat::CkMailMan.new()

# To use a SOCKS4 or SOCKS5 proxy, simply set the following
# properties prior to making any calls that communicate with
# a POP3 server:
# The SOCKS hostname may be a domain name or 
# IP address:
mailman.put_SocksHostname("www.mysocksproxyserver.com")
mailman.put_SocksPort(1080)
mailman.put_SocksUsername("myProxyLogin")
mailman.put_SocksPassword("myProxyPassword")
# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
mailman.put_SocksVersion(5)
# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Set the POP3 server's hostname
mailman.put_MailHost("pop.someMailServer.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.
bundle = Chilkat::CkEmailBundle.new()
keepOnServer = true
headersOnly = false
# Irrelevent because we are NOT downloading headers-only
numBodyLines = 0
success = mailman.FetchAll(keepOnServer,headersOnly,numBodyLines,bundle)
if (success == false)
    print mailman.lastErrorText() + "\n";
    exit
end

email = Chilkat::CkEmail.new()
i = 0
while i < bundle.get_MessageCount()
    bundle.EmailAt(i,email)

    print "From: " + email.ck_from() + "\n";
    print "Subject: " + email.subject() + "\n";
    i = i + 1
end
