Cannot confirm mail forwarding!

Cannot confirm mail forwarding!

I've set up a filter on my main account, for example:
[if subject contains "test" forward to " example@myZohoDomain.com"]

I received an e-mail on my other account ( example@myZohoDomain.com) asking to confirm, with a confirmation code. However the instructions are unclear/outdated.

The message says:
To enter the confirmation code in Zoho,follow the steps below:
  • Login to www.zoho.com/mail
  • Select Mail Settings >> Email Forwarding/POP/IMAP
  • Click on the Verify link corresponding to the email address to be validated, in the Email Forwarding section
  • Provide the Confirmation code in the text box provided
  • Click Confirm 
However, "Email Forwarding /POP/IMAP" is not available. I believe this is from the older UI. When I click on "older settings", I do see the "Email Forwarding /POP/IMAP" section, but nowhere to put the confirmation code.

What's going on?
