# 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();

# Set the SMTP server (obviously, use your SMTP server, not chilkatsoft.com)
$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');
# To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

# To send high-priority email, 
# add the X-Priority header field with the value "1" 
# to indicate highest-priority.
# A value of "3" is normal, which is the same as not setting
# the X-Priority header at all, and "5" is the lowest. 
# "2" and "4" are in-betweens.

# Microsoft Outlook might add the following headers when
# sending high-priority email.

# X-Priority: 1 (Highest) 
# X-MSMail-Priority: High 
# Importance: High 

# The X-Priority header alone is enough to make the email high-priority.

$email->AddHeaderField("X-Priority","1");

# 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;
}

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

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