crookesa on "[Plugin: Contact Form 7] Sending emails not working"

Thanks very much for the link to the other post, I didn't see that topic at all when looking for a solution.
The problem seems to be with the cPanel MX settings for the Email Routing. It was set to Local Mail Exchanger which means it got lost when it hit the local server. I have since changed it to use Automatically Detect Settings which looks at my MX records and forwards to Google App mail servers straight away.
I have tested it and it seems to be working. I'll monitor it and report back if it goes again.
Thanks l3l2ad
