You can give other people permissions on your imap folders.  E.g. you
can say, that '' can be read (beside yourself) by user
'foo' and that user 'boss' can delete mails there.

See e.g. [1] for some more details about supported permissions.

I use it in kerberos cross realm setups, to give myself access to my
mailbox from both realms (e.g. both 'ensc@REALM' and 'ensc@OTHER-REALM'
have admin/all rights on the mailbox).

In some customer setup, we create shared mailboxes, so that non personalized
mails (e.g. to '' or '') are delivered to
those mailboxes which can be accessed by a group of people.

You can give also other people temporarily access to your mailbox
(e.g. during vacation).

ACL support was one of the killer features of gnus; I knew only some web
frontends (horde) and cli tools which support modification of acls.

ACLs are changed seldomly, but I do not want to miss them.

I can test it and can perhaps provide access to cyrus imap server.
