impa for secondary accounts

impa for secondary accounts

Hi, 
is it possible (if it is : HOW TO ???)
to use imap for a secondary accout configured on zohomail ?

i want to use my zoho account for personnal use. No problem to use imap.
and i configured another mail  account, (e-mail from my provider). i'm not able to use it in imap mode like the other one, the "redirection tab" is not accessible in the "parameters tab" for this account.

thanks
