The directory structure for user at example.com exists. Just not in the 
regular mysql database. If I create a fake passdb system it works:

passdb {
   driver = static
   args = nopassword=y
}

However - it leaves the system wide open for anyone. Basically - only 
master users are going to log in and manage stored spam for regular 
users. The master user will be able to spoof being the regular user to 
review stored spam.
