I have a problem to send email in wordpress website contact form.
I use contact form 7 for contact form and WP mail SMTP for mail server connect setting.,
My website testing server can received email from contact form 7 without WP mail SMTP setting.
But production server cannot received email although showed “Thank you” message.
So, I set up SMTP setting using plugin.
It also still fail to received email from contact form. It has error message as shown below.
Please give me some advice to solve this problem.,
Thanks.
