# 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 != 1) {
    print $mailman->lastErrorText() . "\r\n";
    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 != 1) {
    print "Connection to SMTP server not closed cleanly." . "\r\n";
}

print "Mail Sent!" . "\r\n";
