Outlook 2003 with Exchange server 2003 permits me to send mail from
unauthorised user id, as it does not require an authentication before using
smtp. The way currently around this issue seems to be restricting Ip
addresses from which mail is sent. Is there a way to mandate smtp
authentication by logging into an account before sending mail on exchange.

I realise the question wasn't clear. Well let me try again.
I use exchange protocol on Outlook2003.
Is there some way in which I can prevent imposters within my organisational
LAN from sending mail to others, as if it were from me?
In POP3 protocol we have the option of requiring the user to authenticate
the account before using SMTP. Is a similar mechanism available to ensure
authentication before sending mail on my id

I would ask this in an Exchange group as it would be a server-side operation, not client side.
