6.5.3 Editing IMAP ACLs

ACL stands for Access Control List. ACLs are used in IMAP for limiting (or enabling) other users access to your mail boxes. Not all IMAP servers support this, this function will give an error if it doesn't.

To edit an ACL for a mailbox, type G l (gnus-group-edit-nnimap-acl) and you'll be presented with an ACL editing window with detailed instructions.

Some possible uses:

• Giving "anyone" the "lrs" rights (lookup, read, keep seen/unseen flags) on your mailing list mailboxes enables other users on the same server to follow the list without subscribing to it.
• At least with the Cyrus server, you are required to give the user "anyone" posting ("p") capabilities to have "plussing" work (that is, mail sent to user+mailbox@domain ending up in the IMAP mailbox INBOX.mailbox).
