Postfix + IMAP + Cyrus-Imap

引用:

1. 使用自已獨立的資料庫。
2. 提供容量限制 (quotas) 的功能來替代系統中原有的 filesystem quotas。
3. filesystem quotas 它不會提醒你容量是否快要滿了，當容量滿時，filesystem quotas 就立即停止接收新的 mail。
4. Cyrus-IMAP 提供的 "soft-quotas" 功能，它會偵察使用了多少空間以及數量，當接近容量限制 (quota) 時，

    它會親切的提醒你，要你做好準備。一旦 quota 界滿時，它會再次的向 user 發出警告，期間如有 mail 傳入，

    它會退回 (bounced back) 該 mail，並且解釋說該使用者信箱已滿。這樣貼切的功能，讓遺失 mail 的機率降為更低。

[A.] 方式一，修改 /etc/imapd.conf; 增加下列兩行

autocreatequota: -1
createonpost: yes               # 讓信箱自動建立

      方式二，因為Cyrus-IMAPd uses it's own Maildir format and not mboxes，所以要用cyrus-imapd製作mailbox的程式
      執行
         cyradm localhost –user cyrus
         或者 cyradm –auth login localhost –user cyrus
                                                              (–user 後面接管理員帳號 (在 imapd.conf 裡設置的 admins: cyrus))

localhost> cm user.test        # 建立mailbox
localhost> lm                      # list mailbox
localhost> setacl user.test cyrus all
localhost> listacl user.test

[Q.] 測試 Cyrus-IMAP 的認證是否有正常運作
         imtest -m login -a test localhost             # test為使用者名稱
