Test Expressions

The message characteristic and operator settings determine the type of data that is entered as the test expression. For example, if the message characteristic being tested is the Attachment name, and the operator is Matches regex, enter a regular expression as the test expression. If the message characteristic being tested is the Spam probability and the operator is Is over, enter a number between 1 and 99 as the test expression.

Multiple Test Expressions

Some tests allow multiple test expressions. (If a test supports this, it is noted in the message characteristic description.) To specify multiple test expressions, enclose each expression in quotation marks, and separate them with commas. For example, to compare the selected message characteristic against two email addresses, enter the addresses in the following format:

 "address@domain.com","address2@domain.com"
