Delivery Diagnostic error (Could not instantiate mail function)

[Konyvtar2023]

Hi
I have a complain about your delivery system.
I sent awhile some newsletters, but the process have suddenly disconnected.
My knowledge are settings (emails, forms, etc. ) should be valid.
I run a delivery diagnostic, and I gave an error message:

“FAILED (Could not instantiate mail function.)
– Try to remove the return path on main settings.
Read more. – Try to set on main setting a sender address with the same domain of your blog: brodykonyvtar.hu (you are using info@brody.iif.hu) ”

Would you help me this problem? I will appreciate that.

Hi, it’s your provider blocking the email functionality of the server. You should ask them the reason.

A note: we do not provide a delivery service, the plugin sends the emails using the WP mailing functionality which, in turn, uses your provider hosting services.
