I have question related to Forwarded mails from my Support alias on to the Zohodesk email. 

Presently, all the forwarded mails are getting converted into tickets and hence choking my Zoho Desk with unwanted SPAM tickets. 

Is there a way \, I can use filters on relevant emails to be converted in Tickets only ? 

Also, how we can tap to get the same subject emails landing into the same Ticket no?

Looking forward for a reply

Regards
