Using Keywords in Content Filtering
When the content filtering is enabled, all messages are checked against
every keyword sequence that is specified in the selected list of keywords.
A keyword may contain any characters, including punctuation symbols,
spaces, and other word separators. Keywords are case insensitive.
You can use ‘?’ character in a keyword to match any character in that
position in the keyword and ‘*’ to match any number of characters.
Keyword examples:
To represent ‘?’ or ‘*’ characters themselves in keywords, use ‘\?’ and ‘\*’
sequences correspondingly. To represent ‘\’ character, use ‘\\’.
For example, to match the '*** SPAM ***' string, enter '\*\*\* spam \*\*\*'.
example
Matches any message text or subject that
contains the word ‘example’.
another example
Matches any message text or subject that
contains the ‘another example’ text. Words
‘another’ and ‘example’ have to be separated
with exactly one space character.
co?p?rate
Matches any message text or subject that
contains - for example - words ‘corporate’ or
‘cooperate’.
another*example
Matches any message text or subject that
contains words ‘another’ and ‘example’
separated with any number of characters. For
