You have a virus. There’s a new Email virus that comes disguised as either a screen saver (.scr) or some other kind of seemingly harmless file, that when you open it it infects your computer, then uses the names and email addresses in your address book to spread itself. It sends itself to one addres, while displaying another address from your address book in the "from:" field, so as to confuse people who are trying to track it down. The person infected uses aone.net.au for their smtp server, and presumably their ISP. You might want to find a good anti-virus program and check your system out. I’m pretty sure it’s someone from this board because it’s always addresses to info@congenitaladrenalhyperplasia.org. The last 4 were from aone.net.au so it looks like you’re sending out lots of them, whoever it is.
