SMTP using SOCKS5, SOCKS4 Proxy

Demonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 proxy. Ruby

require 'chilkat'

success = false

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

# The mailman object is used for sending and receiving 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
# an SMTP 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 SMTP server.
mailman.put_SmtpHost("smtp.chilkatsoft.com")

# Set the SMTP login/password (if required)
mailman.put_SmtpUsername("myUsername")
mailman.put_SmtpPassword("myPassword")

# Create a new email object
email = Chilkat::CkEmail.new()

email.put_Subject("This is a test")
email.put_Body("This is a test")
email.put_From("Chilkat Support <support@chilkatsoft.com>")
success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com")

# Call SendEmail to connect to the SMTP server and send.
# The connection (i.e. session) to the SMTP server remains
# open so that subsequent SendEmail calls may use the
# same connection.  
success = mailman.SendEmail(email)
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

# Some SMTP servers do not actually send the email until 
# the connection is closed.  In these cases, it is necessary to
# call CloseSmtpConnection for the mail to be  sent.  
# Most SMTP servers send the email immediately, and it is 
# not required to close the connection.  We'll close it here
# for the example:
success = mailman.CloseSmtpConnection()
if (success != true)
    print "Connection to SMTP server not closed cleanly." + "\n";
end

print "Mail Sent!" + "\n";
