Weird emails received randomly

[Guest]

Greeting all,

Lately at my office we've got about 2 person received this following weird email so far and randomly, although i knew it must be done by someone "outside" the company, but how can i prevent that, and how they do that by sending as my company's email address (which is not existing)?

This is the actual email descriptions:
"Dear user,

From: administration@(mycompanyname).com
To: (one of your user in the AD)
Subject: Email report

Anyone have any idea how this email created, how to filter it. Or anyone whom experienced this before.

Thanks in advance!

Unfortunately I believe it's quite easy to send an email so that it appears
to come from another email address.

For example see this product...

Some computer viruses will look in your address book and send out copies of
itself to all your contacts BUT it will make it look like these email came
from someone else not you. That way if any emails it send can't be delivered
you don't get any "Return to sender messages" - so you are not alerted to
the fact that your computer is infected. Clever?

The only thing you can do is change your email address.

I think that is the Bagle virus. See
