require 'chilkat'

#  The mailman object is used for sending and receiving email.
mailman = Chilkat::CkMailMan.new()

#  Any string argument automatically begins the 30-day trial.
success = mailman.UnlockComponent("30-day trial")
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

#  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 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 via the HTTP proxy 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";
