I'm having trouble with emails, until 2 weeks ago everything was fine, but spam started coming to my mailbox in larger quantities from a form from my prestashop store.
Then seeing this spam, the hosting company made some changes to curb this attack. After inserting a security measure, the spam is no longer there.... but not all emails are coming through either.
The domain is in OVH.
Emails are received on Gmail inbox in google Workspace.
Dns theoretically set ok.
Mails that do not arrive are for example with an order from the prestashop store, but already the usual mails from another mailbox or even from the contact form on the same page normally arrive.
I noticed that the emails that do not arrive are the "automatic" ones, sent for example with an order.
I would be happy to check these settings with someone who knows about Google Workspace, Gmail, DNS MX, etc.
