Autoresponder not working

Dear,

The automatic autoresponder of email to who fills the form is not working. I have tested here, I am not receiving any emails. How to fix this problem?

Unfortunately, we are experiencing some delays with emails. The emails shall be sent to the recipients in the order they are queued in. If the emails are still being not sent after several hours, please let us know. We will be happy to take a look again.

We are sorry for the inconvenience this may have caused.
