This figure shows how an address rewriting rule rewrites the uppercase ORG in the preceding e-mail address to lowercase. The Pattern (LHS) uses the operators and wildcards $* @ $- .ORG. The $* matches anything on the left side of the at sign (@); the @ represents an exact match; the $- matches exactly one token in the example e-mail address john.jones@home.ORG; and the .ORG represents another exact match. The Result RHS operators $1@$ rewrites the uppercase ORG to lowercase. The description of the rule is "Changing the uppercase to lowercase".
