Contact form 7 is show message successfully sent mail but I didn’t receive any email, I used hostgator service and I think maybe the host kill my email when it submitted (I read from FAQ) and I don’t know how to config some settings on host, other I think maybe the contact form 7 not work with wp 3.4.1.
I check again it work when send email to gmail, yahoo mail is not receive any mail I check in spam mail but I don’t see any mail
