Emails forwarded to me are delivered in Trash

Emails forwarded to me are delivered in Trash

Hello, 

For some reason, emails that I have set to forward from my GMail account' rules to my Zoho address are delivered directly to my Zoho Trash folder. 

These emails are automated results from a Google Form that notifies me of new additions to my form. 

If I manually forward an email from GMail to Zoho, it's delivered correctly. 

Can you help?
