Notify email without autentication

Hi,
on my NAS, would i like to active the notify by email.
in the menu i can configure Server and port, but MUST configure the user and password too.
My provider auth my connection SMTP by ip addres, and doesn't require authentication U/P.
I had try to remove the configuration of user and password, but the System ask me tu put, because need.
how can i fix?
a other question it is how can i custome the FROM addres ofthe email? in the notify menu i don't see a fild for have that.
thanks
