[courier-users] Read-only-IMAP / shared folders

[Bernd Wurst]

Hi.

My customer asked for a setup where several IMAP accounts use the same mailbox
and some have full access and some have read-only access to the mailbox.

Is there a way to have this? Is it possible without setting up shared folders?

If you have access to several other users you have a shared folder anyway.
Look at "maildiracl": maildiracl -set /home/user2/Maildir INBOX.Notes anyone
-r

No, that's the very definition of shared folders.

It's a little difference if I only have some virtual accounts pointing to the
same maildir or if I have to set up shared folder indexing and stuff...

Is there a way to set up folders that are only shared with some users and not
with everyone?
Or is this done by denying access for "anyone"?

Gruß, Bernd

This can be done with virtual shared folders and access control lists. The
accounts must be different accounts, the server configured for shared
folders, and the IMAP client must fully support IMAP public namespaces.

If the IMAP client also fully supports IMAP ACLs, the owner of the account
will have full control over who has access to which folders, directly from
the IMAP client. Otherwise, the permissions will need to be adjusted
manually using the maildiracl command.

All of this will require some non-trivial amount of setup. Once it's set
up, though, additional shared folders and accounts can be trivially added.
