We're running an exchange server here. I noticed the other day that the administrator email account is blasting out emails to random email addresses for the domain, like "email@example.com, firstname.lastname@example.org, email@example.com, etc..." They are bogus addresses and are thus being returned as undeliverable. The emails vary in subject but are usually "Your password has been successfully updated" or "Your Account is suspended for Security Reasons". The attachment is always a zip file with a definite virus embedded. Zip file name is "important-details.zip". I've scanned with everything I have and poured over all of the stores. i can't find where this is originating from. I'd imagine it is a virus that's launching these emails. I attempted to change the administrator password to no avail. Anyone have any ideas?
