Zoho Mail setting in Em Client

Using ‘New Account’ > ‘Other’ I have tried all the recommended incoming and outgoing server settings (as suggested by zoho support and many others) but Em Client fails to set up the account with these settings (just returns the ‘failed’ message
Can anyone help?
Thanks

eM Client does not support the protocol for the Zoho mail server, although it used to (albeit unintentionally).  See the following post for more info:
