Improve this question What I tested ? I added my personal mail and another mail that ended with dynaroof.com (comma separated). I always received mail whenever I hit submit with delay of 1-2 minutes at my personal mail. But no mail was received at info@dynaroof.com or another mail of dynaroof.com. I tried several plugins including contact form 7, gravity form. I faced same issue there. The mail is working correctly though, I checked spam, I also sent mail to info@dynaroof.com from my personal email, it was a success. So, I came to conclusion that its not sending mail to same mail domain dynaroof.com. What could be possible culprit of this behaviour ?
