Creating Mail Application Defenses
2. In the Total Number of Phrase Matches to Verify Before Rejection field,
specify whether the filter will search the entire message for key words,
or whether it will stop searching for key words if the minimum number
of matches is met:
Minimum—Select this option if you want the filter to stop
searching and fail the message if the minimum number of key
word matches is met. This is based on the number that you enter
in the previous step. The filter will reject a mail message once the
minimum number of key words are matched.
All—Select this option if you want the filter to continue searching
the message for key words after the minimum number of key
word matches is met, for auditing purposes. After searching the
entire message for key word matches, the message is rejected.
3. The Phrase List table provides the list of phrases that will be filtered for
this Application Defense. The table contains three columns:
Before—This column indicates whether a space is required
immediately before the specified phrase to match the filter. An
asterisk (*) indicates that the phrase will not match unless there is a
space immediately in front of the phrase.
Phrase Text—This column lists each phrase for which the filter will
search.
After—This column indicates whether a space is required
immediately after the specified phrase to match the filter. An
asterisk (*) indicates that the phrase will not match unless there is a
space immediately following the phrase.
To add a phrase, click New. To modify a phrase, highlight the
appropriate row and click Modify. The Keyword Search: Phrase Edit
window appears.
Configuring the Keyword Search: Phrase Edit window
When you click New or Modify beneath the Phrase List area, the
Keyword Search Phrase Edit window appears. This window allows
you to add or modify character strings (known as “key words”).
Follow the steps below.
1. In the Text field, type the text you want to filter. You can include any
printable character, as well as spaces. However, the character string
must consist of at least two characters.
Note: Some special characters, such as a space, will be displayed in the Key Word list
using their hexadecimal equivalents.
