I'm trying to change the confirmation email for one of my Zoho accounts so I can move that email address to my other Zoho account.  

In the Profile section I have added a new email address (yahoo) and clicked 'Make it Primary'.  I've then asked for the confirmation email to be sent to the yahoo account but the email is not sent, or at least it doesn't appear in the yahoo mailbox.  I've been waiting 30 minutes for it.

Any ideas?
