Converting existing pop3 account to Zoho amil account for second domain

Converting existing pop3 account to Zoho amil account for second domain

I recently verified a second domain of my account & pointed the MX record to Zoho.
Now that Zoho is hosting the mail account, I cannot access my email via pop3 (because it is internally hosted) AND
Zoho does not allow me to set up an additional e-mail account that is internally hosted.
The only option seems to be to add pop3 e-mail accounts.

How do I add a Zoho hosted e-mail account for myself (not an additional user)?
