But I want to add yahoo as IMAP in Zoho.... that is I want to IMAP yahoo in Zoho just as I can IMAP in any email client (like Microsoft Outlook 2007, Thunderbird, etc)

I want to keep in sync the send / receive emails at yahoo and zoho servers.

I think it would be great if something like this is possible as most of the yahoo email users are sick of the interface and want to shift some another system.
