Contact Form7 not working

It doesn’t work

You gotta be way more specific ??

I have been given the site with this form in place.
If you test it you can see a red message error.

I need help.

Thanks

Contact Form 7 is trying to send an email, and the email server is rejecting it. So now you have to find out what is causing the failure.

Either post screenshots of all your config so can see what you’ve done or install the plugin below which will show the exact error in the Email Log.

• I get an error message with a red border. So, how can I solve this?
• Postman SMTP Mailer
