SMTP Question

[Martin Searancke]

Most mail packages have the ability to let a user log in when sending mail.
(Outlook for example.) I was looking at this and had a couple of
questions...
Is this part of the SMTP standard?
Can this be used to let authorised people relay through a server?

Thanks
Martin
