It's a load off my mind to know that even if the ISP that runs my IMAP server should lose my mailboxes (it's happened to me before), I will lose at most one day's worth of mail.

现在我放心了，因为我知道即使运行我的IMAP服务器的ISP丢失了我的邮箱(我以前碰到过这种事情)，我最多也就丢失一天的邮件。

If there are many messages and your mail client loses the connection to the IMAP server while moving them (as happens often over a slow network link), this capability is for you.

如果有许多消息，而您的邮件客户机在移动它们时与IMAP服务器的连接断开(在慢速网络链接上常常发生这种情况)，那么可以使用这一能力。

For example, the Cyrus IMAP server comes with the Sieve system (see Resources) for automatically filtering E-mail when it's delivered to the mailbox of the user.

例如，Cyrus IMAP服务器附带了Sieve系统(请参见参考资料)，它可以在电子邮件传递到用户的邮箱时，对其进行自动过滤。
