Using wildcards

Wildcards are characters that take form of an asterisk (*) followed or preceded by a particular character (-s) and are used to replace other characters in strings, e.g. *@company.com, *test*, *@company*.

In CodeTwo Exchange Rules, wildcards are case-insensitive and may be used to define email addresses and keywords in strings. Therefore, it is possible only for Sender, Recipient, Subject and Body conditions.

Tip

Please note that you can use asterisk individually before or after a string of characters, simultaneously in front and after a string or inside a string, e.g. if you define the wildcards: *@company.com, mike@company.*, *@company.*, mike@com*pany.com, the following strings will be recognized: xxxxx@company.com, mike@company.xxxxx, xxxxx@company.xxxxx, mike@comxxxxxpany.
