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@$2.org
rewrites the uppercase ORG to lowercase. The description of the rule is "Changing the uppercase to lowercase".
