bogus email address for me in our lists??

[lynda.kane]

Hi,

Can someone explain how an email address like this:

9366@realhealth-online.com   (my emaail is lynda@realhealth-online.com)

can get onto a List 0 - I don't have a list 0!! in listmail and then send me our outgoing mailing to me at that address??  Completely baffled.

Thanks,

Lynda
