Usage

Configurable settings	Default Value	Description

serverTypes	Array of Types	Built in list of valid services for authentication
errors	Array of Errors	List of all error codes, there description and some help text on what the issue may be
username	NONE	Set to the username to be used for authentication
password	NONE	Set to the password to be used for authentication
passwordType	plain	Currently on 'plain' is used, possible future enhancement to allow form based password encryption

logger	Null Logger	\Monolog\Logger if passed to constructor, this is used for all logging
sslCheck	true	If true, then perform SSL verification on the connection. NOTE If using POP or IMAP, this should be set to 'false' as some bug causes PHP imap_open to still check SSL when using non-ssl connection
authenticated	EMPTY	Status of the authentication, set to True after user sucsesfully authenticates or False otherwise

smtpLocalHost	NONE	Local hostname for SMTP authentication, not currently used, will most likely be removed in a future revision.

Setup Logging, not required but good for debug

$logger=new Logger('auth');
$logger->pushHandler(new StreamHandler(__DIR__.'/auth.log', LOGGER::DEBUG));
$logger->info('Auth Script Starting');

After authenticate() has been called, you can check the result of the authentication with :

$result=$auth->authenticated;

SMTP Authentication

$auth=new MailAuth($logger);
$auth->setMailServerUrl('MySMTPServerHostName');
$auth->setServerType('SMTP');
$auth->setSmtpLocalHost('MyLocalHostName');
$auth->setTimeOut(10);
$auth->setSslCheck(false);
$auth->setUsername('MyUserName');
$auth->setPassword('MyPassword');
$result=$auth->authenticate();

SMTPS Authentication

$auth=new MailAuth($logger);
$auth->setMailServerUrl('MySMTPServerHostName');
$auth->setServerType('SMTPS');
$auth->setSmtpLocalHost('MyLocalHostName');
$auth->setTimeOut(10);
$auth->setSslCheck(true);
$auth->setUsername('MyUserName');

$auth->setMailServerUrl('MyPOPServerHostName');
