About Regular Expressions

InterScan Messaging Security Appliance (IMSA) 7.0 treats all keyword expressions as regular expressions. eManager 6.0 in IMSA 7.0 supports the following regular expressions.

 

Change the adjacent <space> to "\x20" for the following in a regular expression:
·   .AND.
·   .OR.
·   .NOT.
·   .WILD.
·   .NEAR.
·   .OCCUR.
·   .(.
·   .).
To match "abc aANDb def", use "abc\x20.AND.\x20def" instead of "abc .AND. def".
