Failed message but entry appears in database

I have the same problem.

I found the problem. The to-email should be an email address from the same domain as the website. Now it’s working Ok.

Though the plugin successfully sends millions of emails every day, there are a host of issues that can stop or delay emails on both the sending and receiving ends. It depends entirely on your local Server & WordPress configuration. You will need to investigate this issue for your particular local configuration.

See Contact Form 7 Email Issues. Most people that work through this information appear to be able to resolve their email sending & receiving issues.

Note that your particular issue is likely to entirely different to that found by PCWebSoft.

It actually was the email notification address for me too – I used a semicolon to separate them instead of a comma. Thanks PCWebSoft and buzztone!
