Paypal Payments not getting "Confirmed" and emails are not sent

[visitmontaione]

Joomla 4.2.5
VirtueMart 4.0.7 10744

Hello, I have setup the payment method "Paypal standard". By the way, after the transaction tested via Sandbox, any emails start (vendor and customer).

I can see, from the backoffice, that the order has been processed, but it is in "stand by" and not "accepted" as setup in the paypal configuration (see attachment).

What do I need to investigate more, and understand if the problems comes from Paypal, Virtuemart or my server?

My hosting siteground says that the website send emails correctly. I am waiting for the reply from Paypal.

Does anyone has the same issue? How do you have solved?

Please note: with other shipping methods, emails are sent and received normally.
