Zoho desk not receving forwarded email

Zoho desk not receving forwarded email

Hello,
I'm posting here because I'm facing a very annoying issue. All the mail that a forwarded to my zoho desk address are not appearing as tickets.

- I can create manually a ticket
- I Can send manually a mail to my zoho desk address and the ticket is created

But when I automatically forward a mail from any Gsuite or outlook account it not create any ticket, I don't receive any none delivery mail too.
I think there are a spam filter activated on my account that block it, it's just a supposition.
Can you please help me?

Thanks in advance,
