Emails from completed forms going to 'Junk' folder in Outlook

Emails from completed forms going to 'Junk' folder in Outlook

Over the last week the email address from completed forms has added 'via public.zohoforms.eu' to the address and is being picked up as junk email and people are not seeing the emails.

Do you know why this changed from sending out of Zoho Forms with the email I set-up to adding 'via public.zohoforms.eu' abd causing this issue.

Is there a setting I can set or change in Zoho Forms to get this to work as before?
