How to setup email notification using Web UI (Hotio Docker image)

I have searched and read anything related to email configuration I could find, and I have tried all the combination but nothing works, here is the email server config details:

Option Value
Protocol/Method IMAP
Mail server box.server.email
IMAP Port 993
IMAP Security SSL or TLS
SMTP Port 465
SMTP Security SSL or TLS
Username: Your whole email address.
Password: Your mail password.

Combination I have tried:
box.server.email:465
smtps://box.server.email:465
smtp://box.server.email:465
smtps://box.server.email
smtp://box.server.email

Errors I get are, EOF, too many colons etc.
