I am running a Drupal 6 site using the SMTP (6.x-1.0-beta5) and the PHPMailer (6.x-2.2) modules for messaging. I configured SMTP and PHP messages, successfully sent and received test messages.
I am using the Organic Groups module and trying to utilize the messaging functions in it, for example receiving notifications for administrator users regarding membership approval.

Drupal isn't sending any mail. When I checked the recent log entries, it reports this error.

Could not locate PHPMailer library

In /admin/messaging/settings I use HTML Mail (PHPMailer) as the default sending method.

Please help me to resolve this issue.

The module relies on the PHPMailer class to send HTML mail. So to send HTML e-mails using Messaging you first need to install PHPMailer.

Check the README.txt file at /messaging/messaging_phpmailer/ for PHPMailer installation instructions.
