Error message when completing the contact form

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.

??Try not to focus on “I have not made any changes to the code and it worked a month ago when i last tested it” – your emails are no longer sending and it’s almost certain that something, somewhere changed to stop them.

The plugin is working for me on many different websites and several different servers. Any issue you have is almost certainly due to something on your local WP install.??
