I and another member of our club have received a few e-mails
with our club's short name in the topic. I'm not yet sure if
all members have received them, but this is more than a
little disconcerting. I went ahead and opened one of them,
but nothing was inside, making it all the more
disconcerting. Our e-mail provider found no viruses
associated with them. Neither of us recognized the sender
address (ouzcmzb@yahoo.com) and have deleted all we have
received. Any ideas as to the cause of this, and moreover,
how to prevent?

Thanks

There is probably a virus on one of your club members' computers.

You can set some preferences which will prevent this kind of thing:

A club officer must set them. You probably want to turn off "Allow
email from anybody". Note that if your broker is mailing your club
address, it will bounce if you turn off this option.
