use chilkat();

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

#  Any string argument automatically begins the 30-day trial.
$success = $mailman->UnlockComponent("30-day trial");
if ($success != 1) {
    print "Component unlock failed" . "\n";
    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 = new 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 != 1) {
    print $mailman->lastErrorText() . "\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." . "\n";
}

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