Configuration SMTP Server

[skull]

Hi friends, if I'm using a SMTP server that requires authenticity, username and password, how can I configure it?

I have this:
- Under CONFIG

Description: E-Mail
Type: EMail
SMTP Server: smtp.myserver.com
SMTP HELO: smtp.myserver.com
SMTP email: [email protected]

- Under USERS -> Admin -> Media

Type: EMail
Send to: [email protected]
Use if severity: All marked
Status: Enabled

Then, how can I setup it? Where do I set the password?

Very thanks all
