Please reject and bounce emails that fail SPF

Please reject and bounce emails that fail SPF

To Zoho.
A large percentage of spam coming in completely fails SPF checks.
I am talking a complete FAIL, not a neutral.
There is no need to have these come in and waste time sifting through them.
Please reject these with a bounce message to the sender (or at least give users that option). That will serve 2 purposes:
  1. If an email is legitimate, the sender will receive the bounce and be able to take it up with their email admin
  2. Any mail provider (ie as Zoho does) that monitors the number of bounced emails received back from its users sending emails will more easily be able to detect spammers

Thankyou
