# 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 = chilkat2.MailMan()

# 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.SocksHostname = "www.mysocksproxyserver.com"
mailman.SocksPort = 1080
mailman.SocksUsername = "myProxyLogin"
mailman.SocksPassword = "myProxyPassword"
# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
mailman.SocksVersion = 5
# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Set the SMTP server.
mailman.SmtpHost = "smtp.chilkatsoft.com"

# Set the SMTP login/password (if required)
mailman.SmtpUsername = "myUsername"
mailman.SmtpPassword = "myPassword"

# Create a new email object
email = chilkat2.Email()

email.Subject = "This is a test"
email.Body = "This is a test"
email.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)
    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!")
