Gmail IMAP settings

Gmail IMAP settings

Missing +OK response upon connecting to the server: * OK svwall.zoho.com IMAP4 Server (Zoho Mail IMAP4rev1 Server version 1.0)"

I'm trying to read my Zoho mail in the Gmail Client. I've tried both POP and IMAP configurations, but every time I get them, it lasts only for a while and then the configuration falls. Please help!
