While Courier doesn't do this "out of the box", it can be made to do so fairly easily.

The first thing you need to do is patch Courier to deliver messages with a different umask. Edit courier/module.local/deliver.c, find the line that reads: umask(077); Change the value to 007.

That's it. Courier can now deliver to shared mailboxes. You have a couple of options as to the best way to inject messages into those mailboxes, though.

You could create a "sharedfolders" group on your system, create a set of shared folder collections as documented, and then change the permissions of the folders, adding set-gid. Just set up aliases in courier to point directly to the mailboxes.

Your could also add a "sharedfolders" user AND group to your system (that group should be the user's primary group), and set up your shared folders in that user's home directory. In this setup, you'd need two sets of aliases. First, courier would need to alias "sales" to "sharedfolders-sales", and then you'd need .courier-sales set up in the sharedfolders user's home directory to deliver messages to the "sales" mailbox.

In either case, any users that need access to the shared folders would need to be members of the "sharedfolders" group, and would need the rest of the configuration as specified in the documentation for shared folders.
