Subscribe2 Trouble sending emails

I have been using Subscribe2 for quite awhile successfully. A few weeks ago, updates stopped going out. I’m not 100% sure but it seems like it coincided with my WordPress upgrade to the latest version.

I’ve checked with my host and there doesn’t seem to be anything changed on their end.

I’ve tried using smtpmail plugin but can’t get that to work either. It won’t connect to my gmail account. It timesout.

So.. can anyone help ?
I have 1400+subscribers
There is a 100 email per hour limit on my host.. how many emails would Subscribe actually send out if it’s sending to 1400 people. How many recipients are BCC in an email?

Do you think they are getting blocked as spam? It’s only subscribe2 emails that are not going out. Other mail from my domain is sent.

Any hints as to why smtpmail.php won’t work??
I’m using the following settings:

function wp_mail_to_smtp(&$phpmailer) {
$phpmailer->Mailer = ‘SSL’;
$phpmailer->SMTPAuth = true;
$phpmailer->Host = ‘smtp.gmail.com’;
$phpmailer->Port = ‘587’; <– I’ve tried 465 too!!
$phpmailer->Username = ‘[email protected]’;
$phpmailer->Password = ‘######’;
}
?>

Any help appreciated. I’m desparate to get updates working again..I can’t afford to move site to more expensive hosting package.
