I have not yet succeeded in getting Contact Form 7 Version 2.4.3 to send an email.
I installed and configured WP-Mail-SMTP Version 0.8.6, but I could not get it to connect to my smtp server (smtp.gmail.com). I configured instead to use php, and it successfully sends a test message.
I believe I have correctly configured both per the instructions here: http://angstrey.com/index.php/2009/04/22/how-to-send-e-mail-with-wordpress-from-godaddy-windows-hosting/, although I don't use Go Daddy.
Can anyone suggest some troubleshooting tips to get this going?
