new in zoho mail: cannot setting IMAP access in my mobile device

hi guys
i set the IMAP access enabled.

what i did in my mail client (i use my own domain, let say mydomain.com):

email address: bondan@mydomain.com
username: bondan@mydomain.com
password: [my email password]
imap server: imap.zoho.com
security: ssl/tls
authetication: plain
port: 993

the email client says 'your username or password may be incorrect. NO [ALERT], invalid credential'

can someone help me?
