Discusses SMTP authentication when sending email in Perl.

# file: SmtpAuthentication.pl

use chilkat;

# About SMTP Authentication when sending $email->
$mailman = new chilkat::CkMailMan();
$mailman->UnlockComponent('anything for 30-day trial');

# Set your SMTP server's hostname
$mailman->put_SmtpHost('smtp.comcast.net');

# If your SMTP server requires a authentication, set username/password
# $mailman->put_SmtpUsername("***");
# $mailman->put_SmtpPassword("***");

# Your SMTP server may or may not require authentication.  It often depends
# upon the location where the SMTP client is making the connection.  If the
# SMTP server is behind a firewall, it is often administered such that clients
# connecting from the same side of the firewall (i.e. within the network) can
# send email without authentication.  However, connections originating from
# outside the firewall DO require authentication.  This is quite often the
# case with cable modem and DSL ISP's.  
# If authentication is required, different SMTP servers support different authentication
# methods, some of which are more secure than others.  In the least secure scenario,
# your login/password is transmitted in clear-text (i.e. unencrypted) over the TCP/IP
# connection to the SMTP server.  This is with the "LOGIN" method.
# The "PLAIN" SMTP authentication method is effectively no better because the information
# is simply Base64 encoded.  The CRAM-MD5 and NTLM methods are secure because the
# login/password is sent encrypted.  However, if your connection to the SMTP server is
# SSL, or if you are using the STARTTLS option, it doesn't matter if the authentication
# method is LOGIN or PLAIN because the TCP/IP connection is SSL anyway.
# By default, Chilkat will choose the most secure authentication method available
# (as announced by the SMTP server during the initial "hello" handshake).
# If for some reason there is a problem, or if you desire less-secure authentication,
# you may explicitly set the SmtpAuthMethod property to: "LOGIN", "PLAIN", "CRAM-MD5", or "NTLM".
$mailman->put_SmtpAuthMethod("LOGIN");

# Create an e-mail object
$email = new chilkat::CkEmail();
$email->put_Subject("How to send e-mail in the Perl programming language");
$email->put_Body("Email sent from a Perl script");
$email->put_From('Chilkat Support <support@chilkatsoft.com>');

# Add a few recipients...
$email->AddTo("Matt",'matt@chilkatsoft.com');
$email->AddTo("TagTooga",'admin@tagtooga.com');

# Send the email
$success = $mailman->SendEmail($email);
if (! $success)
    {
	$mailman->SaveLastError('lastError.txt');	
    }
