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

#  Any string argument automatically begins the 30-day trial.
success = mailman.UnlockComponent("30-day trial")
if (success != True):
    print "Component unlock failed"
    sys.exit()

#  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()

email.put_Subject("This is a test")
email.put_Body("This is a test")
email.put_From("Chilkat Support <support@chilkatsoft.com>")
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()
    sys.exit()

#  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."

print "Mail Sent!"
