Pin Option

The  Message Store option specifies a list of IMAP mailbox names -- in common terminology, folder names -- to protect from  deletion or modification except by the Message Store Administrator. The format is as follows: "     ", where  ,   and    are the IMAP mailboxes to be protected (note that spaces can be used in mailbox names), and   is the separator between each mailbox.

For instance, if a Messaging Server administrator has used to move certain folders to a specified partition and wishes to ensure that the folders stay on that specified partition, rather than getting deleted and recreated on another partition, (for instance, has moved " " and " " folders to less expensive storage), then the administrator will also want to "pin" the folders in question, e.g.: msconfig&#x3e; set store.pin Trash%Spam
