how to set up zoho mail to delete popped mail from Yahoo

Hi,
When setting up my Zoho mail to pop my yahoo mail account, I noticed an option for zoho to delete mail in yahoo inbox. If my memory is correct,when I delete popped mail from my Zoho inbox, Zoho is able to automatically delete the same email from Yahoo inbox. How do I find those particular settings again so I can make that choice? I have tried looking in the settings area where I would expect to see these options, but no luck so far. Thanks, Jay
