Keyword expression does not match semicolons in Hosted Email Security (HES)

Summary

The keyword expression failed to match the word within the message body of the spam email.

In Hosted Email Security (HES) match module, semicolon is used as a separator of expressions. Thus, if you use a semicolon (;) in a keyword expression, it will split the keywords into multiple parts.

Semicolon is not in RegEx standard escape characters. It can be used normally in regular expressions, but it has a different function in HES so it cannot be used in expressions.

As a workaround, use the regular expression standard of ASCII. Replace the semicolon with the following:

  • \73 (Oct)
  • \x3B (Hex)

For more details about expressions, refer to this article: About Keyword Expressions.
