Having trouble forwarding mail, POP, IMAP

I have tried using the forwarding mail service to forward a copy of my zoho mail to my gmail account. After confirming, I still never received any forwarded mail. Next, I enabled POP for all messages and was able to get my welcome email from zoho only in my gmail inbox, but nothing else. I also followed your instructions and tried setting up the imap account in K-9 Mail totally leaving gmail out of the mix. I still only got the welcome email from zoho. I am not able to get any other emails forwarded in any way out of my zoho inbox. Also, I can't find the welcome email anywhere in zoho. Is there a setting or detail I have missed somewhere?
