Add better SMTP error handling

[tvb]

It seems the SMTP plugin is giving me problems. I'm not sure for how long this has been a problem but it might be for quite some time..

SMTP Error: data not accepted.
The error occurred near ../core/lib/vendor/class.phpmailer.php:1234

1232:         //Only send the DATA command if we have viable recipients
1233:         if ((count($this->all_recipients) > count($bad_rcpt)) and !$this->smtp->data($header . $body)) {
1234:             throw new phpmailerException($this->lang('data_not_accepted'), self::STOP_CRITICAL);
1235:         }
1236:         if ($this->SMTPKeepAlive == true) {

The user is however registered just fine.

Ok, im not sure what the problems was. But it might have something todo with the following error.

550 5.4.5 Daily sending quota exceeded

I had a spam run on my forums with over 1500 users created in a very short amount of time.

@tvb have you since resolved this issue? Perhaps adding some more error handling around this problem will help.

[tvb]

Yes, perhaps. I am still not sure what the initial problem was. Maybe update the mailer class completely and add more error handling could help.
