you can exclude all local accounts, but there's no option to use wildcards to exclude accounts. I suppose it could be added though - maybe a regex rather than wildcards though.
3.11 Option - DefaultGoodDomains Name: DefaultGoodDomains Section: Users Purpose: A list of users to never process. Default Value: "” Range: Bar delimited list of domain name or domain SID values
Specifies a list of good domain names - users will be processed if their detected domain matches one on this list. The current user’s domain is automatically added. To allow local users to be processed, use the “Local” keyword. You can enter either domain SID’s or text domain names, for example S-1-5-21-1234567-432324,SafeBoot,McAfee,Local You can also use the DomainNameIndex value to apply a SID>Domain Name lookup so you can use text names rather than SID values. You should add at least the names of the common domains in your environment to ensure users are processed.
