Hi There. I'm hosted on Hostgator. I'm using W3 Total Cache. binyanhaolam.com is the site
When I send a test using the following contact form, no feedback is generated, and no mail received. Same when I use a to="firstname.lastname@example.org"
No difference if I deactivate W3 Total Cache.
I checked at hostgator, and the MX records are set to remote exchange, with google's addresses (there's a gapps account linked with the domain)
