Email spoofing - Exchange

A single user at a company is receiving emails from himself that he did not send, and the emails are also going to other users at the company.

So, user1 is getting emails that have this:

From: User1@domain.com
To: user1@domain.com; user2@domain.com; user3@domain.com
Subject: Hello

How can I stop these emails from happening.

They do not happen a lot, maybe one or two a day.

Current environment:
Server 2003 Standard
Symantec Mail Gateway as spam services

One thing to look at is setting up correct SPF records for your domain. This authorize only certain servers to be on the "whitelist" of who can send emails out.

You then need a spam filtering software that has the ability to check the spf.
