I've enabled email debugging, and I get the following message: Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.

Here's the full details:

I'll try to go through the library and determine what specifically is causing it later tonight.

I'm using an external SMTP server, so I shouldn't have to set up sendmail locally, right? Otherwise my email wouldn't be going out at all (which it is.) I've verified that my php.ini settings are correct (and since I'm using XAMPP, I've checked to make sure it is right in the php and apache folder, since it might be using either one.)
