发送者：

发信人的邮件地址或姓名。

收信人：

邮件的接收者。

CC:

Only the CC recipients of the message.

BCC:

Only the BCC recipients of the message. Obviously this can only be applied to outgoing filters.

Sender or Recipients:

The sender's email address or the name of the sender or the recipients of the message.

目标：

邮件的主题行。

指定的邮件头：

Any header including custom ones.

If a message uses a header more than once, Evolution pays attention only to the first instance, even if the message defines the header differently the second time. For example, if a message declares the Resent-From: header as "engineering@example.com" and then restates it as "marketing@example.com", Evolution filters as though the second declaration did not occur. To filter on messages that use headers multiple times, use a regular expression.

消息体：

在邮件的正文中搜索。

表达式：

(For programmers only) Match a message according to an expression you write in the Scheme language used to define filters in Evolution.

Date sent:

根据邮件发送的日期过滤邮件。首先，选择您想要邮件匹配日期的条件，例如在指定日期之前或之后。然后，选择日期。过滤器会比较邮件的时间标签、当前运行时的系统时间或一个特定的时刻、以及您从日历中选取的日期。您还可以选择比较相对于当前时间的一个时间段，例如2~4天之前。

Date received:

与“发信日期”选项的工作方式相同，但它比较您收到邮件的时间和您指定的日期。

标签：

Messages can have labels of Important, Work, Personal, To Do, or Later. You can set labels with other filters or manually.

分数：

给邮件设置一个大于0的分数。您可以设置一个过滤或改变一个邮件分数，然后设置另一个过滤移动您已评分的邮件。邮件评分没有任何特殊的标准：它只是您给邮件标记的一个数字以便其它过滤器对它们进行操作。

Size (kB):

根据邮件大小排序，以千兆字节(KB)为单位。

状态：

根据邮件状态过滤。邮件状态可以是回复，草稿，重要，已读或者垃圾邮件。

跟随：

Checks whether the message is flagged for follow-up.

Completed On:

附件：

Checks whether there is an attachment for the email.

Mailing List:

根据邮件来自的邮件列表过滤。这个过滤操作可能会遗漏一些来自某些列表服务器的邮件，因为它检查X-BeenThere信头，这是用于确定邮件列表或其它邮件分发者的。而来自列表服务器的没有正确设置X-BeenThere的邮件就不能被过滤器捕获了。

正则表达式匹配：

(For programmers only) If you know your way around a regex, or regular expression, this option allows you to search for complex patterns of letters, so that you can find, for example, all words that start with a and end with m, and are between six and fifteen letters long, or all messages that declare a particular header twice. For information about how to use regular expressions, check the man page for the grep command.
