I've created a patch that adds a feature that is helpful to my setup. If 'parent_dir_umask' is set in the configuration file, any missing directories in the home directory path are created.
The home directory itself is created according to the 'umask' setting, 'parent_dir_umask' is only used for intermediate directories that might need creating.
This is useful to me, as I pull user information from a PostgreSQL database. This allows a new account to be created just by populating the database. The directory gets created the first time the user logs in (by Dovecot) or mail is received (by the MTA).
As the patch is of modest length, I have included it below. I hope my meager skills are not an insult to the beatiful Dovecot code base!
Thanks, David
