The Virus is called "Mimail.A".
The Subject usually says "Your Account" followed by strange letters but variations will appear.
The Sender is usually "admin@your_domain"
Most virus checkers should have a patch to detect this virus by now, so I would suggest updating your virus checkers.
Our work has had this virus almost 100 times in the past 2 days, but our MailSweeper has stopped all instances of it.
