# 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.
set mailman [new_CkMailMan]

# 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:
CkMailMan_put_SocksHostname $mailman "www.mysocksproxyserver.com"
CkMailMan_put_SocksPort $mailman 1080
CkMailMan_put_SocksUsername $mailman "myProxyLogin"
CkMailMan_put_SocksPassword $mailman "myProxyPassword"
# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
CkMailMan_put_SocksVersion $mailman 5
# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Set the SMTP server.
CkMailMan_put_SmtpHost $mailman "smtp.chilkatsoft.com"

# Set the SMTP login/password (if required)
CkMailMan_put_SmtpUsername $mailman "myUsername"
CkMailMan_put_SmtpPassword $mailman "myPassword"

# Create a new email object
set email [new_CkEmail]

CkEmail_put_Subject $email "This is a test"
CkEmail_put_Body $email "This is a test"
CkEmail_put_From $email "Chilkat Support <support@chilkatsoft.com>"
set success [CkEmail_AddTo $email "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.  
set success [CkMailMan_SendEmail $mailman $email]
if {$success != 1} then {
    puts [CkMailMan_lastErrorText $mailman]
    delete_CkMailMan $mailman
    delete_CkEmail $email
    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:
set success [CkMailMan_CloseSmtpConnection $mailman]
if {$success != 1} then {
    puts "Connection to SMTP server not closed cleanly."
}

puts "Mail Sent!"

delete_CkMailMan $mailman
