email setup in winbox?

I have setup the ip of our mail server under email in winbox on 4.6.

I have set port 25, the email addy in the from field

what is needed in the user and password field? Does it need admin access to the mail server?

I have tried setting up the those fields with an email addy and password to access that email account…

User and password configuration is necessary, when SMTP server asks for the authentication.
