TLS error with sending mail in PHP

I am getting a TLS error when trying to mail from PHP.
Here is the error: authentication failure [SMTP: STARTTLS failed (code: 220, response: Start TLS negotiation)

I am using the sample code in the knowledgebase for the PHP code like this (with appropriate code for username, password, smtp host, etc): This code has been working for years and now all the sudden it is giving an error. The code below was using the default port (25) and I changed it to 587. I have email set up on my cell phone and it uses smtp.hcpawpals.org and port 587 and i can send and receive email on my phone OK.

require_once "Mail.php";
$from = "Sender ";
$to = "Recipient ";
$subject = "This is a test email sent via php";
$body = "This is a test email";
$host = "[Mail Server Name]";
$username = "[email protected]";
$password = "email_password";
$headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject);
$smtp = Mail::factory('smtp', array ('host' => $host, 'port' => '587', 'auth' => true, 'username' => $username, 'password' => $password));
$mail = $smtp->send($to, $headers, $body);echo "mail sent"; ?>

has there been changes to the way PHP sends email with mail.php?

the code to use localhost (email without smtp) works just fine. Code like this:

$to = "[email protected]";
$subject = "this is the subject";
$message = "this is the message";
$headers = "From: [email protected]";
if (mail($to, $subject, $message, $headers)) {
// mail went OK
} else {
// mail has errors
}


Thanks,

Sorry, I thought the forum was not the same as tech support. I can log into the [email protected] email with smartermail and use the same password as in the php code. And I login OK. I have changed the php code to smtp authenticate with a different email address [email protected] and the correct password and it still gets the same error. I can login to smartermail with the same password for [email protected] that I use in the php code and it works just fine. This code was working and had been working for several years. then all of the sudden a few days ago it failed. Don't believe it is a password issue.

Here is the php code I am using...
$from = "Calendar Info <[email protected]>";
$to = "Warren Smith <[email protected]>";
$subject = "Calendar Pictures Uploaded";
$body = "Calendar Pictures have been uploaded.";

$host = "[smtp.hcpawpals.org]";
$port = "587";
$username = "[email protected]";
$password = "*******";
$headers = array ('From' => $from,
'To' => $to,
'Subject' => $subject);
$smtp = Mail::factory('smtp',
array ('host' => $host,
'port' => $port,
'auth' => true,
'username' => $username,
'password' => $password));

 

I set up debug to look at the smtp tls authentication. Here it is: Seems the TLS is not negotiating properly.
