当使用标准 IMAP 客户端（不是 Outlook，而是 Thunderbird 甚至 Telnet）登录 Exchange 2003 时，我看到一堆不是邮件文件夹的文件夹：
. list "" "*"
* LIST (\HasNoChildren) "/" Drafts
* LIST (\HasNoChildren) "/" Notes
* LIST (\HasChildren) "/" Tasks
* LIST (\HasNoChildren) "/" "Junk E-mail"
* LIST (\HasNoChildren) "/" Journal
* LIST (\HasNoChildren) "/" Tasks/sjakie!
* LIST (\HasNoChildren) "/" INBOX/000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001111011111111111111111111111111111111111111111111111011111111111111111111111111111111111111111111111111111111111111111111111011111111111
* LIST (\HasChildren) "/" "Sent Items"
* LIST (\HasNoChildren) "/" "Sent Items/Junk E-mail"
* LIST (\HasNoChildren) "/" Outbox
* LIST (\HasNoChildren) "/" Contacts
* LIST (\HasNoChildren) "/" Calendar
* LIST (\HasNoChildren) "/" "Deleted Items"
* LIST (\HasChildren) "/" INBOX
* LIST (\Noselect) "/" "Public Folders/"
还有许多其他文件夹（联系人、日历等）。
有没有办法告诉 Exchange 停止在 IMAP 中向我显示这些项目？
