I have been trying to setup contact form 7 to send an email to my address without any success. I did some research and notice a few others were having similar issues. I am using WP-Mail-SMTP plugin for the smtp setup. I tested sending a test message with this plugin and its fine. However when I try it with contact form 7, it would just say 'fail to send mail'. I m trying to understand how would contact form 7 pickup the settings from wp-mail-smtp?
