XF 2.1 Is there a way to automatically reject emails with more than two periods in the username?

The star is a wildcard that matches literally any text, from nothing (empty match) to a series of arbitrary characters (including dots). The important part is what you add around it. A pattern of *.* matches anything that includes at least one dot. *.*.* requires at least two dots to match, *@*.* requires at least one dot after the @ to match, etc.
