I can't get either PHPMailer or SMTP to work in Drupal 7. The mail does not send, and I get error messages about missing files:
page not found04/29/2011 - 18:03sites/all/libraries/loader/loader-min.js
I also get
Error sending e-mail from sender@gmail.com to recipient@gmail.com : SMTP Error: Could not connect to SMTP host.

I have yui3 installed, but there is no loader library that I could find on the yui site.

I am using gmail, and followed the instructions, so I think I have it set up properly. phpMailer worked with Drupal 6.
Any suggestions?

Thanks,
Jim
