This design presents a reasonably secure system; as long as each voting user has one and only one acceptable E-mail account, there is reasonable assurance that users could not vote twice.
这种设计可以得到一个比较安全的系统；条件是每个投票的用户都有且只有一个可以接受的电子邮件帐号，这样就可以保证每个用户都不会投两次票。
In this example, one address will always receive e-mails of the build status, and another E-mail address will only receive e-mails of failures.
在此例中，一个地址始终接收构建状态电子邮件，另一个电子邮件地址将仅接收有关失败情况的电子邮件。
I know only a handful of people with just one E-mail address, but I know many with three or more, and not all of these people understand automatic forwarding.
