well, your system users do not have no domain, %d is empty therefore. 
Therefore, the mkdir(/var/mail//erickom/Maildir) contains the two // . 
Actually, I'm not sure whether you can keep a domain (%d), but auth to an 
userdb, that does not support domains. Well, you could return a domain 
with extra fields.

But: erickom at example.com, erickom at nowhere.org, and
erickom at metropolitan.org.za would be authentificate successfully
to the system user erickom, but all three users would have another 
mail_location because of the %n.

Do you actually need to support the domain %d part in mail_location?
