Email Not Auto-Forwarding

Email Not Auto-Forwarding

Until today, my Zoho Mail had been auto-forwarding perfectly to my other Email account. I like to do that because I can pick it up with my email client....which therefore notifies me about incoming mail. But today I noticed I was getting mail in Zoho that never got forwarded. So I tested things.....made sure I could send mail straight to both accounts, and I can. Made sure my email client is working with another account, and it is. The only thing that doesn't seem to work is forwarding from Zoho to my Earthlink account.
