Sorry I guess I was not clear enough, i'm working with virtual user directories, not 'real' users. I'm talking about this script in the maildroprc. The script does indeed called maildirmake. This is so directories are automatically created when mail arrives for the first time. The script is not doing that and returning an error instead. Basically i'm trying to do what many others have tried but few have actually done, have maildirs created by maildrop without patching or manually addidng the dirs. Thanks,
