Business mail account added in to invite and wait for pending?? Why?

Hi,

I added my domain name, add some accounts tested and it all worked well, but I couldn't add my previously used mail on zoho business mail. my domain is sircini<dot>com. I really need to add info<at>sircini<dot>com 
When I create new account the mail added to invite and waiting for pending.. why!?

I'm really stuck with these please help me to figure it out...
